A’s Designate Aaron Brooks For Assignment

The A’s announced this morning that they’ve activated right-hander Luis Medina from the 60-day injured list. To make room for Medina on both the club’s active and 40-man rosters, right-hander Aaron Brooks was designated for assignment.

Brooks, 34, signed with the A’s on a minor league deal over the winter and was called up last month to help fill out the club’s rotation mix amid a number of injuries to key veterans such as Alex Wood, Ross Stripling, and Paul Blackburn. He ultimately made four starts for the A’s, pitching to a 5.82 ERA with a 5.59 FIP in 21 2/3 innings of work with a strikeout rate of just 10% against a 6% walk rate. With potential long-term pieces like JP Sears and Mitch Spence currently filling out the rest of the club’s rotation mix, Brooks’s mediocre performance wasn’t enough to justify a rotation spot for the righty now that Medina is healthy enough to take the mound.

Going forward, the A’s will have one week to either trade Brooks or attempt to pass the veteran righty through waivers. Should he clear waivers, the veteran would have the opportunity to reject an outright assignment in favor of free agency should he wish to do so. Despite his lackluster results this year, it’s feasible that a club in need of starting pitching depth could have interest in the righty. After all, he’s a veteran of six major league seasons who has compiled 56 appearances and 32 starts in the majors during that time as a back-end starter and long reliever who enjoyed some success overseas while pitching in the Korea Baseball Organization from 2020-21.

Brooks’s spot both on the 40-man roster and in the starting rotation will be taken by Medina, who the A’s acquired alongside Sears and Ken Waldichuk in the Frankie Montas trade at the 2022 trade deadline. The 25-year-old made his big league debut with the A’s last year and struggled to a 5.42 ERA in 23 appearances, 17 of which were starts. Medina’s difficulties at the big league level were primarily attributable to his unsightly 11.5% walk rate, which clocked in less than ten points below his 21.4% strikeout rate.

Despite those ugly peripheral marks, Medina’s 96.1 mph average velocity on his fastball offers plenty of reason for excitement about his abilities if he figure out his command, and his performance improved as the 2023 season continued with a 4.22 ERA and 4.04 FIP in his final 70 1/3 innings of work last year. Medina’s tantalizing upside made him a strong candidate for the fifth starter role in Oakland entering the season until he found himself sidelined by a grade 2 MCL sprain in early March. Medina has been shelved ever since, but now is healthy enough for the A’s to once again offer him the opportunity to join their rotation alongside Sears, Spence, Joey Estes, and Hogan Harris.
