A’s Select Aaron Brooks

4:02PM: Jimenez has a Grade 2 oblique strain and is expected to miss 6-8 weeks, MLB.com’s Martin Gallegos writes (X link).

11:51AM: The A’s announced this morning that they’ve selected the contract of right-hander Aaron Brooks. Brooks will take the place of righty Dany Jimenez on the active roster, who the club placed on the 15-day injured list with a left oblique strain.

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. That first stint in the majors saw the righty post a 5.82 ERA with a 5.59 FIP in 21 2/3 innings of work across four starts with a strikeout rate of just 10% against a 6% walk rate. Brooks found himself DFA’d earlier this month when right-hander Luis Medina was activated from the 60-day IL, but remained with the club after being assigned outright to Triple-A and will now get another opportunity in the majors, albeit this time in a long relief role.

Despite his lackluster results earlier this year, it’s at least feasible to imagine the righty showing off a stronger performance in his second stint in the big leagues this season. 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. He’s also posted a solid 4.30 ERA in 52 1/3 innings of work at the Triple-A level this year despite the inflated offensive environment of the Pacific Coast League.

Brooks will take the roster spot of Jimenez, who has been a decent middle reliever this season for the club this season. In 23 2/3 innings of work, Jimenez has pitched to a solid 3.04 ERA with a decent 20% strikeout rate. Those solid results have come in spite of extreme wildness, however. The right-hander has walked an eye-popping 17.1% of batters faced this year, a trend consistent with the righty’s career numbers. Since making his A’s debut back in 2022, Jimenez has posted a solid 3.32 ERA (118 ERA+) but has never posted a walk rate below 12.4% in a season, while walking 14.5% of batters faced overall while in an Oakland uniform.

Now sidelined for the foreseeable future with an oblique strain, Jimenez figures to work his way back into the big league relief mix once healthy. With pieces like Lucas Erceg, T.J. McFarland, and Austin Adams likely to attract interest from clubs in need of bullpen help this summer, it’s possible that the A’s will have plenty of room for Jimenez if he returns following the trade deadline even in the likely event that the club holds onto superstar closer Mason Miller.
