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

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.

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%

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.
