Ottoneu Relief Pitcher Drip: Sorting Out the Post-Trade Deadline Bullpens

With the MLB trade deadline behind us and the dust still settling, it can be a bit tricky to sort out all the implications for every player moved in a trade this week. It becomes all the more difficult for relievers — both where they fit in the bullpen hierarchy on their new team and how their old team will handle the pecking order. This edition of the Ottonue Relief Pitcher Drip will be devoted to figuring some of those situations while also recommending some under-rostered pitchers who might find themselves in high leverage roles now.

The White Sox were one of the most aggressive sellers this season, trading away six members of their pitching staff including nearly every reliever who had earned high leverage work this year. Gone are Kendall Graveman, Reynaldo López, Keynan Middleton, and Joe Kelly. That means Gregory Santos is the most likely candidate to pick up save opportunities with Aaron Bummer a possibility as well. I covered Santos the last time this column ran in mid-July and his outlook hasn’t changed much since then. He’s still striking out a decent number of batters and his walk rate is still a pristine 5.0%.

The Royals shipped their closer Scott Barlow off to San Diego at the deadline which means Carlos Hernández will likely step in to handle the ninth inning duties. A failed starter with a hard, riding fastball and a nasty slider, he’s managed to hone the command issues that plagued him in longer outings. He’s cut his walk rate more than four points to just 7.4% this year while also pushing his strikeout rate north of 30%. That’s a definite recipe for success. Beyond Hernández, there really isn’t anyone else in Kansas City’s bullpen worth targeting.

In one of the bigger surprises this week, the Mariners traded their closer Paul Sewald to the Diamondbacks. Seattle already had their closer of the future Andrés Muñoz working the eighth inning ahead of Sewald which makes him the obvious candidate to work the ninth inning now. Matt Brash is almost universally rostered in Ottoneu thanks to his outrageous stuff so the overlooked high leverage reliever in Seattle’s bullpen is almost certainly Justin Topa. He had struggled with a laundry list of injuries with the Brewers, accumulating just 17 appearances across his first three seasons in the big leagues. Finally healthy, he’s been a solid option in high leverage situations for the M’s this year. His sinker-slider combo doesn’t produce a ton of strikeouts but he limits walks and keeps the ball on the ground which is a profile that plays well in Ottoneu.

Joe Kelly isn’t gaining an opportunity to earn more high leverage work because relievers ahead of him on the depth chart were traded away. Instead, he was the guy traded away. He’s joining a Dodgers bullpen that’s had plenty of issues finding consistent performers this year. It isn’t immediately clear where he lands in the pecking order since he’s only appeared in a single game for Los Angeles, coming in during the sixth inning after Caleb Ferguson ran into trouble. His brand of effective wildness is well known by now, though his strikeout rate is now at a career-high 32.3%.

The Cardinals were the other big sellers at the deadline, trading away two relievers from their bullpen. With Ryan Helsley sidelined indefinitely and Jordan Hicks now in Toronto, the obvious choice to work the ninth inning should have been Giovanny Gallegos. Instead, the man who received the first save opportunity on Sunday was JoJo Romero who also worked the ninth inning in a non-save situation yesterday. This is a situation that definitely bears monitoring. Gallegos has been receiving high leverage work in the Cardinals bullpen for four years now so it’s possible they’re trying out different options in the ninth inning to evaluate what they have to work with moving forward. Romero was a highly regarded prospect in the Phillies organization at one point. Both his slider and changeup have whiff rates over 40%, giving him two plus weapons in his arsenal.
