How does the Orioles September roster compare to the opening day roster?
STARTING PITCHERS: Kyle Gibson, Dean Kremer, Kyle Bradish, Cole Irvin, Grayson Rodriguez, Jack Flaherty
The starting rotation has been shaken up, with the original five being Kyle Gibson, Dean Kremer, Cole Irvin, Kyle Bradish, and Tyler Wells. They've since shifted to six starters, with Wells being optioned to Double A Bowie after hitting a metaphorical wall. Rodriguez and Flaherty have joined the rotation.
The Orioles are fortunate to have had a healthy starting rotation for the majority of the season, with only Keegan Akin starting a game outside of the names previously mentioned. They've shifted to six starters to keep everyone rested well and also to manage innings, and it's worked so far.
RELIEF PITCHERS: Cionel Pérez, Danny Coulombe, Yennier Cano, Shintaro Fujinami, DL Hall, Joey Krehbiel, Jorge López, Jacob Webb
Behold, the most changed part of the Orioles roster. Out of this current group, only Danny Coulombe and Cionel Pérez have been in the bullpen all season. Cano has been stellar since a callup near the end of April, Fujinami was a trade pickup in July, Webb and López were waiver claims, while Krehbiel and Hall started the year with Norfolk alongside Cano.
For context of how much this has changed, here's the opening day bullpen: Félix Bautista, Cionel Pérez, Bryan Baker, Danny Coulombe, Mike Baumann, Austin Voth, Keegan Akin, Logan Gillaspie.
Bautista would be on the roster still if it weren't for a UCL injury, Baker was optioned to Norfolk at the start of August, while Baumann had a strong stretch in the majors before struggling and being sent down on August 23. Akin is on the 60 Day IL with lower back discomfort, Voth is in limbo after being DFA'd, while Gillaspie was recently claimed by the Boston Red Sox on waivers.
So, while this roster has had plenty of mainstays, there has been plenty of shuffling around the fringes and even in the starters mix, with the pitching staff unsurprisingly being right in the middle of the roster churn. This roster looks completely different now, and that's a good thing for these Orioles.
