Ottoneu Drip: Finding Under-rostered Pitchers: July 3, 2025

Credit: Kiyoshi Mio-Imagn Images

The search for pitching help is never ending. Between injuries and ineffectiveness, fantasy players are always on the lookout for pitchers who are performing well who can provide some reinforcements. Here are eight starters who are rostered in less than 60% of all Ottoneu leagues.

Under-rostered Starters, Last 14 Days
Player Team IP FIP K-BB% Stuff+ Pts/IP Roster%
Michael Soroka WSN 11.1 1.76 29.3% 95 7.81 57.67%
Eduardo Rodriguez ARI 16 2.90 16.9% 94 5.19 53.68%
Charlie Morton BAL 11 2.36 18.2% 105 5.76 46.63%
Trevor Rogers BAL 15.2 3.41 10.9% 92 5.24 26.69%
Adrian Houser CHW 13.1 2.64 9.3% 94 5.67 21.47%
Justin Wrobleski LAD 16 1.65 20.6% 101 6.89 19.94%
Dean Kremer BAL 12.2 1.51 23.4% 89 7.33 17.79%
Stephen Kolek SDP 16.1 2.23 15.6% 90 6.01 10.74%

Whether or not you believe in Michael Soroka’s resurgence or not boils down to how sustainable you think his home run rate is. He’s currently allowing a 1.52 HR/9 and 15.4% HR/FB, both of which aren’t out of the norm for his career. Under the surface, you’ll notice that he currently possesses a 3.75 xFIP, 3.34 SIERA, and 3.04 xERA, all of which are well below his 4.70 ERA and 4.33 FIP. He’s allowed just nine barrels all season long, is sporting an above average groundball rate, and the highest strikeout rate of his career. Almost all the damage has come against his four-seam fastball and the underlying performance of that pitch was slightly better in June (.304 xwOBA) than it had been during the first two months of the season (.347 xwOBA). I’m willing to bet that his results on the field will start to look a lot more like his peripherals over the next few months.

Eduardo Rodriguez was one of my favorite preseason sleeper picks — I love a veteran pitcher with a recent history of success because they’re so often undervalued, particularly in Ottoneu. It’s been an up-and-down season for Rodriguez; he had a 2.81 FIP through his first five starts, completely fell apart over his next four with 24 runs allowed in 16 innings, and then hit the IL with a minor shoulder injury. He returned at the beginning of June and has allowed just 7 runs in five starts with an excellent 3.1 strikeout-to-walk ratio. The ongoing health of his shoulder is a concern, but this version of Rodriguez over the last month has been a pretty useful starter.

There are three Orioles starters in the table above so I’ll tackle them all here. Charlie Morton has rebounded quite nicely from his miserable start to the season; since rejoining the starting rotation on May 26, he’s posted a 2.90 ERA and a 2.47 FIP across six starts. His start this week was pushed back to Friday thanks to some minor elbow inflammation, so that’s definitely something to monitor. Trevor Rogers has also looked solid since being recalled on June 18, posting a 2.87 ERA and a 3.41 FIP across three starts. Injuries had absolutely derailed his career but he looks healthy now and maybe he can regain some of the magic from his 2021 breakout with the Marlins. As for Dean Kremer, he’s on a nice little run of starts — a 2.61 ERA and a matching 2.60 FIP across his last seven outings. The only thing I can spot in his profile is a sharp increase in the number of splitters he’s throwing. It’s his best pitch so it’s nice to see the results follow.

I featured Adrian Houser in this column a month ago at the start of June and he’s continued to put up solid numbers for the White Sox since then. I noted that his changeup looked like it was fueling a lot of his success this year — that pitch still has a 42.3% whiff rate — but the results on his curveball have also significantly improved. That gives him two excellent secondary pitches to pair off of his bowling ball sinker.

With seven starters currently on the IL, the Dodgers’ rotation has been in shambles for most of the season. Of all the pitchers they’ve churned through, Justin Wrobleski looks like the one who is going to manage to stick around. He’s allowed just four runs across his last three outings with an excellent strikeout-to-walk ratio. His fastball’s 32.5% whiff rate sits in the 94th percentile for that pitch type and it’s a big reason why he’s been able to wrack up the strikeouts. One thing to note for Ottoneu players: the Dodgers have either used Wrobleski as a piggybacked bulk reliever or used an opener in front of him. That means you’ll need to pay attention to which day’s he might be scheduled to pitch and where you place him in your lineup. Head-to-head players will get an additional bonus for rostering him since his outings won’t count against your weekly games started cap — assuming the Dodgers continue to use him as a bulk reliever rather than a traditional starter.

The reason why Stephen Kolek appears in the table above is because his groundball rate is in the 85th percentile among starters with at least 60 innings pitched this year and his home run rate is in the 78th percentile. He doesn’t strike out that many and his walk rate is merely average. If you’re rostering him, you’re banking on those two skills carrying most of his value. The first should be fine but the second could be particularly volatile as the weather warms up.

Come with me, for a moment, down into the clubhouse of your favorite MLB team. Walk through the concrete halls and into the press room. Take a seat and wait for the manager to come in. Listen, you can hear it. Pencils, pens, iPad taps, all preparing to ask questions that press the manager, while also making the person asking them sound cool and trustworthy, like, “You can talk to me, it’s me! I’m cool. I’m not like these other press passers.” Here it comes, the classic question:

Press: What did you see out there with your starting pitcher today?

Ottoneu Starting Pitching Planner: June 30–July 6

Credit: Brad Rempel-Imagn Images

Welcome back to the Ottoneu Starting Pitching Planner. Based on the Roster Resource Probables Grid, I’ve organized every starter slated to start next week into four categories: start, maybe, risky, and sit. The first and last category are pretty self-explanatory. Starters who fall into the “maybe” category are guys you could start if you need to keep up with the innings pitched pace in points leagues or need to hit your games started cap in head-to-head leagues; they’re good bets to turn in a decent start, but you shouldn’t automatically insert them into your lineup. If you’ve fallen behind on the innings pitched pace or you’re really starving for starts in a head-to-head matchup, you could turn to a “risky” starter or two.

I’ve also calculated a “Matchup Score” for each series using a straight combination of opponent’s home/away wOBA, opponent wOBA over the last 14 days, and the park factor for the ballpark the teams are playing in. It’s indexed so that 100 is average and anything above that is a favorable matchup and anything below is unfavorable. That matchup rating informs some of the sit/start recommendations I’m making, though the quality of the pitcher definitely takes precedence. I should also note that I’ve updated the way I’m calculating the park factors for the two new minor league stadiums that the Athletics and Rays are playing in this year; I’m taking the one-year park factors from Statcast and regressing them towards neutral, with the one-year factors increasing in weight as more games are played in those stadiums (those series are still marked in yellow below).

Projections-Fueled Top 30 Pitching Prospects, Midseason 2025 Update

Syndication: The Enquirer

This article takes a look at baseball’s top 30 pitching prospects from a projections-based perspective now that half of the 2025 season is in the books. Jump to the bottom for the updated list!

The projections capture prospect performance across the minor and major leagues in recent years, making use of aging curves, major league equivalencies, league environment adjustments, park factors, and regression to project peak (late-20s) prospect performance. They also capture Stuff+ courtesy of Eno Sarris (only for arms with MLB experience), and, starting this season, velocity (for all minor and major leaguers). They do not capture scouting or amateur performance. For comparison and more methodological detail, you can find the preseason list here, last year’s midseason list here, and an introduction to the projections here.

Starting Pitcher June 2025 Stuff+ Risers & Fallers

Jamie Sabau-USA TODAY Sports

Pitchers seemingly change during the season more often than hitters. By change, I mean their talent level fluctuates as their velocity bounces around, they tinker with their pitch mix, mechanics, etc. So it could be insightful to look at recent trends to help decide whether a pitcher is establishing a new performance baseline. So let’s look at June Stuff+ marks for all qualified pitchers in the month. Whose Stuff+ grade has risen most and whose has fallen? Let’s find out.

Ottoneu Drip: Finding Under-rostered Pitchers: June 19, 2025

Credit: Brad Penner-Imagn Images

The search for pitching help is never ending. Between injuries and ineffectiveness, fantasy players are always on the lookout for pitchers who are performing well who can provide some reinforcements. Last time I ran this column, I focused on eight starting pitchers who were pitching well at the time. This time around, my focus will shift to the bullpen — with three starters sprinkled in for good measure.

Under-rostered Starters, Last 14 Days
Player Team IP FIP K-BB% Stuff+ Pts/IP Roster%
Quinn Priester MIL 17 2.13 16.9% 99 6.35 29.4%
Emerson Hancock SEA 17.2 4.09 10.8% 82 4.92 3.1%
Mike Burrows PIT 15 1.87 27.9% 92 6.22 1.8%

Over his first seven appearances (six starts and one bulk relief appearance) for the Brewers this year, Quinn Priester’s walk rate was an untenable 14.2%. In his six appearances since then (three starts, three bulk outings), his walk rate has been a very good 3.8%. He’s been pitching in the zone a bit more often — he had a 50.9% zone rate during that first stretch and a 55.2% zone rate during the second — while still maintaining an acceptable strikeout rate and an elite groundball rate. The groundball rate alone should give him a high-ish floor for Ottoneu, and the improved command makes him an interesting dart throw. Just make sure to monitor his usage as a traditional starter or a bulk reliever.

Injuries to George Kirby, Logan Gilbert, and Bryce Miller have forced Emerson Hancock into a much more prominent role in the Mariners rotation than the team probably expected. His season stats are being dragged down by two very ugly starts: a six-run, two-out disaster in his first start of the season and a seven-run, five-inning clunker against the Yankees on May 12. I don’t recommend doing this as a frequent practice, but if you remove those starts from his overall stats, his ERA drops from 4.48 to 2.60, his FIP from 4.81 to 4.09, and his Pts/IP rises from 3.05 to 4.26. That is a perfectly cromulent starter in Ottoneu as long as you’re benching him in particularly difficult matchups.

Mike Burrows isn’t the Pittsburgh pitching prospect we’ve all wanted to see in the big leagues (that would be Bubba Chandler), but he’s got a couple of interesting attributes that could make him an interesting pick up in Ottoneu. First of all, his changeup is currently returning a 51.7% whiff rate and a .252 xwOBA allowed. His slider’s xwOBA allowed is even lower at .221, though it’s not getting the swings and misses like his change is. The problem is that his fastball is far too hittable, which means his ceiling is capped pretty low. Still, he’s allowed just three runs total in his last three starts and is running an excellent 6.67 strikeout-to-walk ratio during this stretch. As long as the changeup continues to be a plus plus bat missing weapon and the slider continues to suppress contact, he’ll likely have stretches like this where he looks dominant. The run-of-the-mill fastball will bring him back to earth eventually.

Under-rostered Relievers, Last 14 Days
Player Team IP FIP K-BB% gmLI Stuff+ Pts/IP Roster%
Gregory Soto BAL 6.1 0.54 45.5% 1.03 118 11.63 19.6%
Bryan Baker BAL 6.1 2.59 34.8% 1.53 107 9.88 16.3%
Seranthony Domínguez BAL 6 0.73 36.4% 1.58 116 11.53 13.5%
Garrett Whitlock BOS 7 0.92 36.4% 2.04 94 10.66 59.2%
Greg Weissert BOS 5.2 2.54 12.5% 1.96 97 10.22 7.4%
Reid Detmers LAA 6 0.40 42.9% 1.90 113 11.80 51.2%
Nick Mears MIL 5.1 0.44 38.9% 0.90 103 9.80 29.8%
Louis Varland MIN 5 1.87 22.7% 1.37 103 7.88 54.3%
Brock Stewart MIN 4.2 1.35 10.0% 1.04 112 8.60 24.8%

Let’s tackle all these relievers by team. The Orioles have had a really tough time finding a consistent setup man to pitch in front of closer Félix Bautista. Six different pitchers have recorded a hold over the last week but the three pitchers listed in the table above look like the most interesting of the bunch. Bryan Baker has increased his strikeout rate 10 points this year while simultaneously cutting his walk rate to a career low. Fueled by an absolutely devastating changeup, he’s the guy I’m targeting out of this ‘pen. Seranthony Domínguez is no stranger to high-leverage work, though his inconsistent command means he’s been pretty volatile throughout his career. He’s on a heater right now, allowing just five baserunners over his last nine outings while striking out 16. Acting as the left-handed specialist in the bullpen, Gregory Soto is earning holds at a consistent pace while also providing solid rate stats.

It looks like Garrett Whitlock and Greg Weissert have settled in as the setup options in front of closer Aroldis Chapman in the Red Sox bullpen. Interestingly, both setup guys have earned saves in the last week after Chapman was unavailable for a few days and then used in the eighth inning on Wednesday to face the top of the Mariners lineup. Whitlock has overcome a long injury history and a failed attempt to convert him to a starter to settle in as a high-leverage reliever this year, a role he was familiar with back when he first broke into the big leagues. His strikeout rate has jumped up to 30.1%, though his walk rate is still a little high at 9.2%. Weissert hasn’t been as dominant as Whitlock, but he’s getting high-leverage opportunities and has done well to convert those opportunities into holds and saves.

Across three outings from April 30–May 7, Reid Detmers allowed 12 runs while recording just a single out. Since that low point, he’s allowed a single run in 16 appearances and is suddenly looking like a dominant high-leverage reliever. His strikeout rate is nearly 40% during this stretch and he’s earned six holds and two saves for the Angels. He has been throwing his fastball about two ticks harder than earlier in the season.

His pitch mix looks the same and there haven’t been any big changes to his approach: his zone rate and chase rate are ever so slightly higher during this hot streak, but batters are swinging and missing at his pitches a lot more often. His success might just come down to a harder fastball and better execution.

I included Nick Mears in this column back on May 13 and he had a bit of a hiccup right after that write up; across his next seven appearances after that article posted, he allowed six runs in 7.1 innings while striking out just three. Across his next seven appearances, he’s been a lot better, holding his opponents scoreless while allowing just two baserunners and striking out eight. He’s firmly behind Trevor Megill and Abner Uribe in the pecking order, but he could be working his way back into high-leverage opportunities in the sixth or seventh inning.

The Twins bullpen has been a bit of a mess recently — they’ve lost three games for the team in the past week — but that just means there are new opportunities for relievers to gain the trust of manager Rocco Baldelli. Jhoan Duran and Griffin Jax are probably safe in their roles, but Louis Varland and Brock Stewart could be sneaking into high-leverage work ahead of those two. Varland has transitioned from the rotation to the ‘pen this year and has looked pretty solid as a reliever. He’s got the big fastball and devastating curveball to thrive in the late innings. Stewart has what Stuff+ thinks is one of the very best sliders in baseball. He’s been particularly injury prone during his career and his command can be spotty at times, leading to some volatility. Still, the 35% strikeout rate is nothing to scoff at, and as long as he’s healthy, he should be a high-leverage option for the Twins.


Ranking Small Sample Pitchers

Reinhold Matay-USA TODAY Sports

A couple of weeks ago, I examined four starting pitchers using a small sample of predictive data. It was a half-hearted comparison. I’m correcting that today with a simple FanGraphs download to spreadsheet comparison.

I decided on the stats to use based on work I did for The Process. Here is a look at what early-season stats are most predictive of rest-of-season stats (R-squared values).

I used the two overall STUFH values (BotOverall, Pitching+) and the top two ERA estimators (SIERA, xFIP). Additionally, I wanted to weigh the stats that immediately stabilize (Ball%, SwStr%, Fastball velocity).

One major change, I put all the values on an ERA scale for easier comparison. Three values came in an ERA format, but the others need to be calculated. Here are the formulas I used (also in the provided spreadsheet).

  • Pitching+ ERA: (Pitching+) * (-0.067) + 10.815
  • SwStr%-Ball% ERA: (-19.4472)* SwStr% + 9.985324 * (Balls/Pitches) + 2.672178
  • Fastball Velo (FBv) ERA: FBv * (-0.1416) + 17.339

Here is a link to the values along with the pitchers featured in this week’s waiver wire column. I limited the time frame to just the past two weeks. I use a method that makes the best decision with a small sample.

Not all the values are in the download, so I created a copyable spreadsheet (File, Create a Copy) to paste the pitchers’ stats (cell L4), and then the various ERA values are calculated along with an overall value.  The average ERA can be ordered by using the promote option in cell J4.

In this instance, Brandon Walter stands out with everything looking great, except his 92 mph (4.32 ERA) fastball. He could bomb, but the goal is to make the best decision with little information.

One possible change is to adjust the weightings. I equally weighed the values. Someone can always give more weight to certain values (Pitching+) or just remove others (FBv). For me, the table allows for easy comparison of pitchers. If I were to evaluate each pitcher, I’d look at the above stats. This makes the analysis easier.

Two additions could be included: the first is to add a projection based on the preseason prospect rank (overall and team), the other one is to include the pitcher’s ERA projection (via xlookup).

Let me know if you have any questions on setting up the spreadsheet to help evaluate pitchers with a small MLB data sample.


Ottoneu Starting Pitching Planner: June 16–22

Welcome back to the Ottoneu Starting Pitching Planner. Based on the Roster Resource Probables Grid, I’ve organized every starter slated to start next week into four categories: start, maybe, risky, and sit. The first and last category are pretty self-explanatory. Starters who fall into the “maybe” category are guys you could start if you need to keep up with the innings pitched pace in points leagues or need to hit your games started cap in head-to-head leagues; they’re good bets to turn in a decent start, but you shouldn’t automatically insert them into your lineup. If you’ve fallen behind on the innings pitched pace or you’re really starving for starts in a head-to-head matchup, you could turn to a “risky” starter or two.

I’ve also calculated a “Matchup Score” for each series using a straight combination of opponent’s home/away wOBA, opponent wOBA over the last 14 days, and the park factor for the ballpark the teams are playing in. It’s indexed so that 100 is average and anything above that is a favorable matchup and anything below is unfavorable. That matchup rating informs some of the sit/start recommendations I’m making, though the quality of the pitcher definitely takes precedence. I should also note that I’ve updated the way I’m calculating the park factors for the two new minor league stadiums that the Athletics and Rays are playing in this year; I’m taking the one-year park factors from Statcast and regressing them towards neutral, with the one-year factors increasing in weight as more games are played in those stadiums (those series are still marked in yellow below).
