Reviewing the Rookie Pitchers — Through June 12, 2023
Let’s review some of the rookie pitchers, all of whom were top prospects heading into the season.
Let’s review some of the rookie pitchers, all of whom were top prospects heading into the season.
It’s not quite sh*tposting, but it’s close: I post a cryptic poll on Twitter and just let it do its thing. It is, to frame it in this week’s Internet meme jargon, my “beige flag,” my desire to sow chaos by dripping a drop of blood into shark-infested waters.
Here’s my most-recent artistic masterpiece:

It seemed like Mason, Bryce, and Bobby all tied or set some kind of record this season, each of them one-upping his predecessor from the the prior week or month or whatever it was. It’s all happening so fast, these Millers.
The poll went exactly how I expected: Read the rest of this entry »

There are few things worse than a big bust with one of the first starting pitchers you drafted. Not only because of the practical value they return (or rather, don’t return) but often so much of draft strategy depends on who you choose as your SP 1/2. And when they go belly up, so too quickly can your entire team.
With that said, let’s take a peek at the pitch mixes of a trio of pitching heartbreakers who were elite fantasy options in 2022 and were drafted as such in 2023 but have come crashing down to earth for the first third of the season, possibly blowing up our chances for championships along with them. But instead of the overall, let’s focus on the worst of the worst. That is, which of their pitches have most been the Fredo to our formerly Sonny rosters. Read the rest of this entry »
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.
A few general schedule notes first:
Notable two-start pitchers:
Yesterday, I discussed six fantasy relevant starting pitchers who have most underperformed their SIERA marks. Now let’s flip over to the overperformers.
Two months into the season is a good time to evaluate your team, its strengths and weaknesses. You usually can never have enough pitching, as there’s always someone who gets injured, suddenly loses velocity or effectiveness, and then you’re scrambling. So let’s review the starting pitchers that have underperformed their SIERA marks the most so far. This could be a good target list to trade for that includes pitchers that shouldn’t cost much to acquire.
After rethinking what my Friday column looks like a few weeks ago, I wrote up some under-rostered relievers as the first step in reimagining this Tuesday column. This week, I’ll be looking at a few under-rostered starters who have been performing particularly well the past few weeks. I’ve split the article into pitchers rostered in more than and less than 60% of all Ottoneu leagues to give a good spread of shallow and deep options.
Roster > 60%
| Player | Team | IP | FIP | K-BB% | HR/9 | Pts/IP | Roster% |
|---|---|---|---|---|---|---|---|
| Michael Kopech | CHW | 18.1 | 3.34 | 33.8% | 1.47 | 6.04 | 97.8% |
| Miles Mikolas | STL | 20 | 1.88 | 20.3% | 0.00 | 6.46 | 87.8% |
| Jack Flaherty | STL | 17 | 2.93 | 12.0% | 0.00 | 5.15 | 85.9% |
| Clarke Schmidt | NYY | 10.2 | 2.07 | 18.6% | 0.00 | 6.67 | 73.1% |
You’ve probably heard that Michael Kopech has finally figured things out after really struggling to start off the year. Through his first eight outings, he had a 5.74 ERA that paled in comparison to his ghastly 7.30 FIP. He had allowed a whopping 12 home runs during that stretch, though his xFIP wasn’t much better at 5.78. His strikeout and walk rates were trending the wrong direction and he looked thoroughly cooked. Then, on May 19, he held the Royals scoreless across eight innings, striking out 10 and walking no one. Granted, it doesn’t take an ace to keep Kansas City off the scoreboard but Kopech has proven that it wasn’t just a fluke against a weak opponent. Across his last four starts, including the one against the Royals, he’s posted a 2.05 ERA backed by a 2.56 FIP and it looks like all his command woes have been put behind him; he’s running an outstanding 9.5 strikeout-to-walk ratio during this hot stretch. This stretch of success seemingly stems from a mechanical adjustment to reassert his talent.
Miles Mikolas has also put a rough start to the season behind him. Through his first five starts, his ERA and FIP stood at 7.46 and 5.49, respectively. Since then, they’re down to 1.82 and 2.98 in eight starts and he’s been particularly effective over his last three outings. I don’t think there’s any one thing driving his recent success, it’s simply a return to his ultra-efficient profile after a rough five start stretch in April.
Over his last four starts, Jack Flaherty has posted a 1.88 ERA and a 2.45 FIP with a decent 3.13 strikeout-to-walk ratio. That’s an improvement over his early season work that suffered from far too many free passes. The biggest difference has been a greater reliance on his fastball; he threw his heater around 37% of the time through the first eight starts of the season and that’s jumped up ten points over the last four. Tangibly, that’s resulted in a nearly five point increase in his zone rate and just eight walks during this stretch.
Clarke Schmidt just tossed his best start of the season against the Mariners last week, holding them scoreless over 5.2 innings with seven strikeouts. Across his last three starts, he holds a 2.07 FIP with a 3.40 strikeout-to-walk ratio. To me, the perception of Schmidt’s struggles this year are out of step with his peripherals — his strikeout and walk rates during this streak of strong starts are right in line with his seasonal averages — but two ugly starts against the Rays and Rangers where he allowed 12 runs marr his overall line. I think his improvement is linked to how he’s using his sweeper. In his first nine starts of the year, he located his big breaking ball in the zone a little over 50% of the time. That rate has fallen three points over his last three starts and his whiff rate with the pitch has seen a five point increase up to 32.5%.
Roster < 60%
| Player | Team | IP | FIP | K-BB% | HR/9 | Pts/IP | Roster% |
|---|---|---|---|---|---|---|---|
| Kyle Gibson | BAL | 12.2 | 3.52 | 2.0% | 0.00 | 5.32 | 46.5% |
| Ben Lively 라이블리 | CIN | 18.2 | 5.16 | 15.8% | 1.93 | 3.59 | 20.2% |
| Reese Olson | DET | 5 | 1.48 | 26.3% | 0.00 | 8.16 | 18.3% |
| Dean Kremer | BAL | 17.2 | 3.74 | 16.2% | 1.02 | 4.23 | 12.2% |
Kyle Gibson has been a solid, if unexciting contributor for years. This season, his strikeout rate is down a bit, though it’s been offset by a drop in home runs allowed. A weird seven inning shutout against the Yankees a few weeks ago where he allowed two hits and four walks to go along with three strikeouts is throwing off his strikeout-minus-walk rate you see above. He’s actually been pretty good over his last four outings, with a 2.92 ERA and a 3.20 FIP.
Gibson’s teammate Dean Kremer has also been on a hot streak and it stretches all the way back to the beginning of May. Across his last six starts, he’s posted a 2.55 ERA and a 3.60 FIP with a pretty good 2.90 strikeout-to-walk ratio to back it up. He’s also done this against some of the best offenses in the league — the Braves, Rays, Angels, Blue Jays, Rangers, and Giants — which is a great sign for when he starts facing some weaker teams. His improvement likely stems from his fastball velocity which has now reached a career high of 94.9 mph on average.
A journeyman who has pitched in Korea in two separate stints, Ben Lively is making the most of his time in the majors with the Reds this year. Across four starts, he’s posted a 3.38 strikeout-to-walk ratio with a 3.33 ERA. The problem has been the home runs, particularly at home in the bandbox in Cincinnati; he’s allowed all five of his home runs at home which has caused his FIP to spike to 4.72. He’s a kitchen-sink righty with a fantastic slider fueling his high strikeout rate right now.
I had planned on writing up Alex Faedo in this space, but the Tigers just placed him on the Injured List with a finger injury. He suffers from the same problem as Lively: a fantastic strikeout-to-walk ratio is marred by far too many home runs allowed. Instead, I’ll highlight the prospect Detroit called up in Faedo’s place: Reese Olson. Command issues capped the potential ceiling of Olson despite possessing a wipeout slider. He threw that pitch a third of the time in his first major league start and it returned a 33.3% whiff rate. The thing to monitor for him will be his ability to locate his fastball. If he’s able to figure out his command issues, he’s got the deep repertoire to be able to produce in the Tigers rotation.
Yesterday, I shared and discussed six starting pitchers who have improved their average exit velocity (EV) against the most compared to 2022. While the correlation isn’t strong, there definitely is a positive correlation between EV and BABIP, whereby the higher the EV allowed, the higher the BABIP, and vice versa. Let’s now flip to the pitchers who have allowed a higher average EV this year.
Since 2015, there’s been a small, but positive correlation (about 0.19) between average exit velocity (EV) against and BABIP. In other words, the higher the EV allowed, the higher the BABIP. Of course, there are many other factors involved, as the correlation isn’t very high, but it’s there. And all else equal, a pitcher does desire to induce soft contact versus hard. So let’s find out which starting pitchers have reduced their average EV marks the most compared to last season.

A few general schedule notes first:
Triston McKenzie and Aaron Civale are both on track to be activated from the IL over the weekend. Cal Quantrill was sent to the IL with a shoulder injury, though he probably would have been pushed out of a rotation spot anyway with both Tanner Bibee and Logan Allen thriving in the majors. Monitor McKenzie’s and Civale’s starts over the weekend to see how their stuff is holding up after their injuries. Both should be solid options going forward, though neither has a particularly easy matchup next week.
