Ottoneu SP Drip: Finding Under-rostered Starters

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%

Under-rostered Starters, Last Two Weeks
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%

Under-rostered Starters, Last Two Weeks
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.

I’m rolling the dice on Barria, 6% owned and unmentioned here. I think there might be something there.Then again, maybe not.
