A’s Finalize Opening Day Bullpen

The A’s finalized their Opening Day bullpen last night, announcing that righty Jack Perkins has been optioned to Triple-A. He’ll likely remain stretched out as a rotation option in the minors, per Martin Gallegos of MLB.com. That leaves righties J.T. Ginn and Luis Medina (the latter of whom is out of minor league options) as the final two members of the Athletics’ initial relief corps this season.

There are no 40-man transactions at play here, but it’s notable that the hard-throwing Medina made the club, as he’d have otherwise been designated for assignment. That was hardly a lock, given the manner in which the 26-year-old has struggled this spring. Medina has pitched 7 1/3 innings and allowed six runs — good for a 7.36 earned run average. Small-sample ERA marks aren’t particularly meaningful, but Medina was probably lucky to “only” surrender six runs. He’s been tagged for six hits and walked a whopping nine batters (24.3%) this spring.

Some rust for Medina is understandable, however. He didn’t pitch at all last year after undergoing Tommy John surgery in August of the 2024 season. Medina has never had particularly sharp command, though this spring’s struggles to locate the ball are obviously extreme even by his prior standards. He’s walked 11.4% of his opponents in 149 2/3 big league innings.

The A’s acquired Medina, JP Sears and Ken Waldichuk from the Yankees in the 2022 trade sending Frankie Montas and Lou Trivino to the Yankees. He’s started 25 games for the A’s and made another six relief appearances since, but opponents have roughed him up for a 5.35 ERA. Medina averaged 96 mph on his four-seamer while working primarily as a starter prior to surgery. He’s been sitting 97.2 mph this spring while working in short relief.

The rotation may not have panned out for Medina, but a pitcher with his velocity and a slider that has generated a huge 20.2% swinging-strike rate could have success in a bullpen capacity. The A’s have invested more than a year in the right-hander’s rehab from that UCL surgery, so despite the rocky spring, it’s only natural that they want to give him some leash to see if he can round into form and give them a quality bullpen option. He’s earning just $835K this year and is under club control through 2029.

Ginn has had an even rougher spring. The former second-round pick came to the A’s from the Mets in the trade sending Chris Bassitt to Queens. He’s been tagged for 17 runs on 18 hits, seven walks and four hit batters during Cactus League play. Ginn has fanned nearly a quarter of his opponents and been dogged by a sky-high .385 average on balls in play, but it’s been an underwhelming spring regardless.

Be that as it may, Ginn will get a crack at carving out a role in a wide-open bullpen landscape. He’s pitched 124 1/3 major league innings to date and carries a 4.85 ERA, 24% strikeout rate and 7.5% walk rate. Ginn’s heater has ticked up a bit this spring, and he’s been mixing in more cutters and changeups at the expense of his slider and sinker. He’s a somewhat natural candidate for a multi-inning/swing role, given his prior work as a starter. Even this spring, he’s made four starts.

The A’s will enter the season with a committee approach to the late innings. Veterans Scott Barlow and Mark Leiter Jr. are the only A’s relievers with real late-inning experience — the former as a closer and the latter as a setup man. It’s been four years since Barlow pitched like a high-end closer, however, and while Leiter has continued to see leverage opportunities in recent seasons, he has a lackluster 4.66 ERA dating back to Opening Day 2024.

Barlow, Leiter, Ginn and Medina will be joined by lefty Hogan Harris and right-handers Justin Sterner, Michael Kelly and Elvis Alvarado in manager Mark Kotsay‘s Opening Day ‘pen. Leiter, Barlow and Medina are the only three members of that octet who cannot be optioned to Triple-A, so there’ll surely be something of a revolving door in the Athletics’ bullpen early in the season as they cycle in fresh arms and look to find the optimal combination for Kotsay.
