ERA Equivalent WHIP (or Why Yusei Kikuchi is Unrosterable)

Paul Rutherford-Imagn Images

Every week, I look through my rostered pitchers noting the worst ones and churn them out next week. This week, the Yusei Kikuchi stood out. Someone with a 3.06 ERA and his ERA estimators around 4.50. It was his ERA estimators throwing red flags, but I have other pitchers worse. It was his 1.52 WHIP, third worst among qualified starters behind Kyle Freeland (1.63) and Jack Kochanowicz (1.56). With WHIP being its own Roto category, it has as much weight as ERA but ERA is the mentioned multiple times more often than WHIP. I’m just going to create a simple WHIP to ERA conversion to put both on the same scale.

To get the conversion equation, I used the overall rankings for the NFBC’s Main Event (15 team) and Online Championship (12 team). With them, I ranked the WHIP and ERA values separately. I removed the the first and last 10% of values because the change for them isn’t linear.

With the tails removed and plotted the best remaining WHIP with the best remaining ERA. I did that for each one. Here are the plotted results.

The correlation is nearly perfect, so the correlation equations can be used to convert a WHIP to an ERA equivalent. Here is conversion table.

Equivalent ERA Value for a Given WHIP
WHIP ME Eqiv ERA OC Eqiv ERA
0.70 0.48 0.52
0.80 1.09 1.12
0.90 1.70 1.72
1.00 2.31 2.33
1.10 2.92 2.93
1.20 3.53 3.53
1.30 4.14 4.13
1.40 4.75 4.73
1.50 5.36 5.33
1.60 5.97 5.94
1.70 6.58 6.54
1.80 7.19 7.14
1.90 7.80 7.74
2.00 8.41 8.34

The results for the two league types are close so I’ll only use the Main Event information going forward. Besides the above table, I have created a public Google Sheet (copy by going to File -> Make a Copy) where a WHIP can be entered and an equivalent ERA is spit out.

Kikuchi’s 1.52 WHIP would be equivalent to a ~5.50 ERA. No one is starting/rostering a pitcher with a 5.50 ERA this deep into the season. The high WHIP can’t be ignored and I’m likely to move on where I can find decent options.

Besides Kikuchi, Here are the qualified pitchers who have a WHIP that does as much ratio damage as a 4.50 or worse ERA.

Qualified Starters with an Equivalent ERA Value Over 4.50
Name ERA WHIP equivalent ERA NFBC Main Event Roster%
Kyle Freeland 5.72 1.63 6.15 4%
Jack Kochanowicz 5.34 1.56 5.72 4%
Yusei Kikuchi 3.06 1.52 5.48 98%
José Soriano 3.41 1.51 5.42 98%
Randy Vásquez 3.99 1.47 5.18 42%
Gavin Williams 3.79 1.45 5.05 100%
Luis L. Ortiz 4.40 1.43 4.93 91%
Max Meyer 4.73 1.42 4.87 100%
Sean Burke 4.20 1.42 4.87 28%
Jonathan Cannon 4.66 1.40 4.75 21%
Michael Lorenzen 4.33 1.40 4.75 98%
Zac Gallen 5.54 1.40 4.75 100%
Dean Kremer 4.70 1.39 4.69 81%
Jeffrey Springs 4.72 1.38 4.63 97%
Shane Baz 4.92 1.38 4.63 100%
Andre Pallante 4.23 1.36 4.50 86%
Chris Bassitt 3.80 1.36 4.50 97%

Gavin Williams and José Soriano have been devastating managers’ in the WHIP category but it doesn’t seem as bad with sub-4.00 ERA.

WHIP is probably one of the most misunderstood categories and hopefully I made it easier to understand an expectable value.


Dominant Non-Closing Relievers — May 27, 2025

Mandatory Credit: Brett Davis-Imagn Images

In 12-team mixed leagues and shallower, you’re generally ignoring relievers that aren’t closing games or potentially will be given the incumbent’s missteps. That’s not true in 15-team+ mixed and, especially, mono leagues. In such deeper formats, replacement level for starting pitchers is poor. You’re essentially choosing between a 4.50 ERA, 1.35 WHIP, but with perhaps 10 wins and 120 strikeouts, starting pitcher, or a middle reliever with superior ratios, but fewer wins and strikeouts. Typically, the latter is actually more valuable even if he doesn’t record a single save all season. So let’s dive into some of the most dominant non-closing middle relievers this year who might be a better option than your worst starter.

Overpaying for a Bird and a Song

Robert Edwards-Imagn Images

Last week, the Giants decided to move Jordan Hicks to the bullpen and Hayden Birdsong to the rotation. While some fantasy managers had already stashed Birdsong, he was available in many leagues like these nine NFBC Main Event leagues.

These teams spent 15% to 20% of their yearly budget on a starter projected to be below replacement-level. Unless a manager wore blinders or took some analyst’s hype without any doing their own basic analysis of Birdsong. No line of reasoning points to Birdsong making a difference, and the most likely scenario is that he’s on the waiver wire in a couple of weeks. Read the rest of this entry »


Ottoneu Drip: Finding Under-rostered Pitchers: May 13, 2025

Credit: Bruce Kluckhohn-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. Right now, there’s an absolute dearth of starting pitching available on the waiver wire. I’ve scraped the bottom of the barrel for these nine under-rostered pitchers — four starters and five relievers.

Under-rostered Starters, Last 30 Days
Player Team IP FIP K-BB% Stuff+ Pts/IP Roster%
Colin Rea CHC 31 3.44 13.5% 95 4.51 40.4%
Tyler Anderson LAA 35.1 3.82 13.3% 96 4.99 20.8%
Chad Patrick MIL 31.1 3.05 12.4% 103 4.83 11.6%
Chris Paddack MIN 32.1 4.04 14.7% 95 4.77 7.6%

I covered Colin Rea the last time I ran this column and I still think he’s one of the more interesting starting pitchers out there. The wide pitch mix, arm angle change, and an improved fastball all make him a pretty interesting pick up.

Tyler Anderson isn’t flashy or fancy but he’s a veteran starter with one elite pitch, his changeup. When that pitch is working for him, he can have stretches like this where he’s able to limit hard contact and generate just enough swings and misses. He probably won’t reach the ceiling of his breakout season with the Dodgers back in 2022, but he’s a solid enough starter that can be counted on in the right matchups.

Chad Patrick has filled in capably for the Brewers as they work through all their early season injuries. He’s survived by inducing a ton of weak contact in the air, which has served him well so far, but it’s also the same reasony why his xFIP is 4.42, more than a run higher than his ERA. Still, over his last three starts, his strikeout-to-walk ratio is a very good 4.67 and he’s improved as he’s adjusted to pitching in the big leagues for the first time.

Chris Paddack started off the season with two absolute stinkers, allowing 13 runs in 7.1 innings with more walks than strikeouts. In his six starts since then, he’s allowed just 10 runs in 32.1 innings with a 2.60 strikeout-to-walk ratio. His last start against the Giants was his best of the year; he pitched into the eighth inning, allowing just three hits while striking out six. He’s always been a bit home run prone and he’s been pretty lucky in that regard during this stretch. Still, it seems like he has his signature fastball-changeup combo working for him right now.

Under-rostered Relievers, Last 30 Days
Player Team IP FIP K-BB% gmLI Stuff+ Pts/IP Roster%
Brendon Little TOR 11.2 2.09 22.0% 1.40 116 7.69 36.7%
Mason Fluharty TOR 13.1 2.29 20.5% 0.95 117 8.65 0.9%
Danny Coulombe MIN 11.1 0.47 38.5% 1.34 104 9.96 28.4%
Nick Mears MIL 13 1.89 20.5% 2.13 98 9.17 21.4%
Ryan Borucki PIT 10.2 1.90 20.0% 0.93 115 8.83 8.6%

The Blue Jays have quietly put together one of the best relief corps in baseball and that’s largely thanks to breakout seasons from guys like Brendon Little and Mason Fluharty. Among all pitchers who have thrown at least 10 innings this season, Little leads all of baseball in swinging strike rate. His sinker has been devastating thanks to some mechanical deception and a ton of drop on the pitch. Fluharty might be even more interesting. As a lefty, he’s yet to allow a hit to a right-handed batter this year. Like Little, he’s got some mechanical deception aiding him and a hard cutter that has given right-handed batters fits when it’s located on the inside half of the plate. Little is a little higher on Toronto’s bullpen pecking order, but Fluharty should be seeing some high leverage work soon too.

Danny Coulombe hasn’t allowed a run in almost a full calendar year. Of course, a lot of his 2024 season was spent on the IL, but he’s now run his scoreless streak to 27 games and 26.1 innings. It took a while for the Twins to start giving him high leverage work but he’s finally working the seventh and eighth innings regularly.

The Brewers bullpen has been a bit of a work-in-progress this year after they moved on from their closer Devin Williams in the offseason. Trevor Megill has a tight hold on the ninth inning, but Nick Mears has worked his way into the high leverage mix in the seventh and eighth innings.

Ryan Borucki isn’t seeing that much high leverage work yet, but the guys in front of him in the Pirates bullpen aren’t all that impressive. The biggest difference for him this year are a new splitter and sweeper that are both returning above average whiff rates. Those two pitches have pushed his Stuff+ from merely average up to 109 on the season.

Ottoneu Drip: Finding Under-rostered Pitchers: April 29, 2025

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. Hopefully, these six under-rostered pitchers — three starters and three relievers — can help.

Under-rostered Starters
Player Team IP FIP K-BB% Stuff+ Pts/IP Roster%
Ryan Gusto HOU 22.2 2.70 21.1% 106 5.36 29.4%
Jose Quintana MIL 23.2 3.35 7.5% 82 5.00 19.6%
Colin Rea CHC 18.2 1.50 21.1% 98 6.84 13.2%

Chad covered Ryan Gusto in his Hot Right Now column yesterday. I mostly agree with his assessment:

“So yes, he has looked good so far. But with only 22.2 IP so far this year, I am more inclined to bet on his track record than his early performance with Houston. Double his walks, double his HR, and how are you feeling? There’s nothing wrong with riding the hot streak. That could both net you some short-term gains and give you time to see if that control and HR suppression are legit. But there are other SP out there I am more interested in right now.”

One thing I’d like to add is that Stuff+ really likes Gusto. All three of his fastballs are above league average by that metric and so is his slider. Stuff+ isn’t as enamored with his changeup but that pitch is returning a 37.5% whiff rate which is above average for the pitch type. Sure, the minor league track record isn’t there, but it’s possible Gusto has taken a pretty significant step forward in his development.

I do need to advise some caution because of the contact quality issues Chad mentioned and also because the Astros will likely activate Lance McCullers Jr. from the IL within a few weeks and possibly Spencer Arrighetti a few more weeks after that. It’s very likely Gusto will be relegated to the bullpen once Houston’s starting rotation gets a little more healthy. So, yes, ride the hot hand while you can, but don’t expect Gusto to be a long-term solution for your pitching staff.

I recommended Jose Quintana in my last Ottoneu Drip and I’m honestly shocked he hasn’t been rostered more. All he’s done since that write up is make three fantastic starts, allowing just three runs total. His strikeout-to-walk ratio isn’t great and it seems like he’s relying on a lot of guile to get by, but the results speak for themselves.

The injury to Justin Steele forced the Cubs to add Colin Rea to their starting rotation a few weeks ago. Rea muddled through the last two years as an innings eating member of the Brewers rotation, but he has made three solid starts for the Cubs against some really impressive opponents. Against the Dodgers, Diamondbacks, and Phillies, he’s allowed just two runs in 13.1 innings while striking out 17. That’s enough for me to take notice.

The biggest difference is a four-seam that he’s throwing more than half the time at the expense of his sinker. His repertoire is still deep — six pitches strong — but he’s really emphasized the heater. He’s throwing it about a tick harder than last year with a little more rise and a little more cut and it’s returning a 25% whiff rate and a .334 xwOBA, both above average marks for a four-seamer. He’s also dropped his arm angle by about five degrees which has had a positive effect on the horizontal movement of all of his pitches. The wide pitch mix, arm angle change, and an improved fastball makes him a pretty interesting pick up, though I might wait to see how he does in a few more starts before rushing out to add him.

Under-rostered Relievers
Player Team IP FIP K-BB% gmLI Stuff+ Pts/IP Roster%
Will Vest DET 12 2.80 23.3% 0.83 103 8.64 53.2%
Reed Garrett NYM 11.2 2.02 17.4% 1.74 112 9.83 51.1%
Shelby Miller ARI 11.2 1.94 23.3% 1.93 97 9.29 14.4%

Chad also covered Will Vest in his article yesterday and I don’t really have much more to add. If you’re speculating on saves in Detroit’s bullpen, Vest is as good an investment as any other high leverage option in that ‘pen.

Reed Garrett had a mini-little breakout last summer before burning out in August. He’s still making high-leverage appearances for the Mets this year and he’s been pretty good. The strikeout rate isn’t as lofty as it was last year, but his walk rate is down and he’s only allowed a single unearned run.

Shelby Miller was finally healthy last year but his stint in Detroit’s bullpen of death could have gone better. He latched on with the Diamondbacks this year and is throwing a little harder and added a sweeper to his repertoire. He, too, has only allowed a single unearned run in 11 appearances for the Snakes and he’s already beginning to work some high leverage opportunities for them.

The wave of early season injuries has hit hard and your fantasy baseball team is more than likely feeling the effects. One of my Ottoneu teams has eight pitchers currently on the IL and I dropped two other injured pitchers in my desperate search for reinforcements. Hopefully, these eight under-rostered pitchers — four starters and four relievers — can help you in your own search for pitching help.

Under-rostered Starters
Player Team IP FIP K-BB% Stuff+ Pts/IP Roster%
Tyler Mahle TEX 13.2 2.81 9.4% 90 6.64 48.9%
Andrew Heaney PIT 18 2.75 20.0% 100 5.98 35.5%
Matthew Liberatore STL 18.1 1.94 23.9% 105 6.10 22.3%
Jose Quintana MIL 7 2.46 9.1% 83 6.49 9.5%

Tyler Mahle is finally healthy after working back from Tommy John surgery in 2023 and a shoulder injury last year. At his peak, he was a strikeout generating machine, producing a 27.1% strikeout rate across three seasons from 2020–22. He hasn’t reached that same level of effectiveness yet, but his first four starts this year have been promising. So far, he’s allowed just two earned runs and eight hits across 19.2 innings, and it seems like the command issues that limited him to just 1.2 innings in his first start are behind him. The velocity on his four-seamer hasn’t returned all the way — and it might not — but he’s getting more induced vertical movement on the pitch than ever before. Opposing batters aren’t swinging and missing against his secondary pitches yet, but the whiff rate on his heater 36.2% of the time! He’s gotten a bit lucky in the batted ball department so I’m sure some regression is coming, but as long as he’s healthy, he looks like he can be a useful starter in all fantasy formats.

Andrew Heaney has been a frequent recommendation in this column over the last few years. He’s the type of pitcher who has hot streaks where he looks incredibly impressive for a time but he isn’t consistent enough to deserve a high roster rate. He’s started off this year on a heater, allowing six runs across 18 innings in his first three starts with a phenomenal 20.0% K-BB%. He’s adjusted his repertoire to feature three different variations of his sweeping breaking ball — Statcast classifies them as a curveball, slider, and slow curve but they’re all generally the same shape with different velocities. He’s also added a sinker to his mix which gives him another weapon to keep batters off his four-seamer. These adjustments to his arsenal have my attention and I’m interested to see if they can help him reduce the amount of hard contact he allows off his heater.

After struggling in the starting rotation for a season and half, Matthew Liberatore found some success pitching out of the bullpen late last year. The Cardinals moved him back to the rotation to start this year and his first three starts of the season have been fantastic from a peripherals standpoint even if the actual run prevention hasn’t been up to snuff. He’s struck out 18 and walked just one in 18.1 innings and he’s managed to work around the platoon issues that have been a problem for him throughout his career. You can chalk that up to a greater emphasis on his changeup and cutter and better command of his entire repertoire.

After signing late in the spring, the Brewers called up Jose Quintana to make his season debut last week and he held the potent Diamondbacks offense scoreless over seven innings. At 36 years old, his best years are probably behind him, but he’s been a useful innings eater for a few years now. One thing to note: he threw his sinker more than half the time in his first start and more than half the balls in play off him were on the ground. Something to keep an eye on if you’re looking to add him.

Under-rostered Relievers
Player Team IP FIP K-BB% gmLI Stuff+ Pts/IP Roster%
Randy Rodríguez SFG 8.1 -0.09 41.9% 1.73 117 9.67 47.7%
Bryan King HOU 7.1 0.71 39.3% 0.97 98 10.75 26.3%
Phil Maton STL 8.1 0.99 33.3% 1.21 101 10.31 16.5%
Gabe Speier SEA 6.2 0.63 36.4% 1.32 123 10.43 4.9%

Many teams are still sorting through the pecking order in their bullpens as they figure out which guys they can trust with high leverage opportunities. The four relievers listed above aren’t necessarily pitching in the ninth or eighth inning, but their peripherals are so good that they could find themselves in those spots sooner rather than later.

Randy Rodríguez has struck out more than 40% of the batters he’s faced so far this season and the Giants are starting to give him more and more high leverage work as a result. Tyler Rogers has been their long-time setup man but Rodríguez’s high-octane stuff fits the role a lot better.

After the Astros traded away Ryan Pressley this offseason, a spot towards the back of their bullpen opened up. Bryan King has quickly filled that opening by also striking out more than 40% of the batters he’s faced. As a left-hander, he’ll likely get high-leverage work when facing pockets of left-handed batters in the late innings, giving him some specific usage patterns.

The Cardinals didn’t really have many good setup options in front of their All-Star closer Ryan Helsley. In steps Phil Maton. He quickly grabbed the eighth inning role in St. Louis and doesn’t really have many competitors for the role.

Injuries wrecked Gabe Speier’s season last year but he’s healthy and firing bullets at the back of the Mariners’ ‘pen. Like King, Speier should see some specific usage patterns as a left-handed reliever and the impending return of Matt Brash could see him pushed down the pecking order in a few weeks.
