Cardinals sign Aaron Wilkerson to minor league contract

The Cardinals announced that Aaron Wilkerson has signed a minor league deal, and the right-hander has been assigned to Triple-A Memphis.  Wilkerson had been pitching in the Reds organization on another minors contract until earlier this week, as KPRC 2’s Ari Alexander reported that Wilkerson triggered an opt-out clause in that deal.

It has been almost six years since Wilkerson’s last big league appearance, as the righty posted a 6.88 ERA across 35 1/3 innings with the Brewers from 2017-19.  Now 36 years old, Wilkerson’s career has seen consisted of a pair of trips abroad (pitching with NPB’s Hanshin Tigers in 2022 and with the KBO League’s Lotte Giants in 2023-24) and a few other stints in the minors with MLB organizations.  Wilkerson has pitched with the Dodgers, Athletics, and Reds without any further calls to the Show.

This year, Wilkerson has a 4.17 ERA over 18 starts and 95 innings for Triple-A Louisville, with a modest 20.7% strikeout rate but an outstanding 4.5% walk rate.  A .249 BABIP has undoubtedly contributed to Wilkerson’s success, and his 15% homer rate continues his trend of having some trouble keeping the ball in the park in both the upper minors and during his brief time as a Major Leaguer.

Wilkerson’s work in Louisville wasn’t enough to get him a look in Cincinnati, as the Reds have turned to a couple of top prospects (Chase Petty, Chase Burns) and more established starting options when having to fill holes in the rotation this year.  The Cardinals’ rotational depth chart is also pretty crowded, yet the Wilkerson signing is intriguing within the context of the July 31 trade deadline. Since St. Louis could be looking to move Erick Fedde, Miles Mikolas, or long reliever Steven Matz, it behooves the Cards to have an experienced starting depth at Triple-A should a vacancy suddenly appear on the team’s pitching staff.
