Cubs righty lands on 15-day IL with groin strain

The Cubs announced to reporters that right-hander Jameson Taillon has been placed on the 15-day injured list with a “mild to moderate” left groin strain, via Jordan Bastian of MLB.com. Taillon had been the scheduled starter for Thursday night’s game against the Dodgers, but righty Javier Assad has been recalled and will take the ball instead.

Taillon, 31, joined the Cubs over the offseason on a four-year, $68M deal. That came on the heels of a strong two-year run with the Yankees, where he made 61 starts over 2021 and 2022, tossing 321 2/3 innings. He posted a 4.08 ERA in that time along with a 21.9% strikeout rate, 5.7% walk rate and 37.1% ground-ball rate. That solid stretch did much to undo an injury-prone label that previously surrounded Taillon. He underwent Tommy John surgery as a prospect in 2014 and underwent the procedure a second time in 2019. But in both instances, he returned and posted good results, leading to his current career ERA of 3.85 over 801 2/3 innings.

This groin strain has popped up seemingly out of nowhere, as Taillon was scheduled to start Thursday night’s game until this news broke. Just this past weekend, he tossed five scoreless innings against the same Dodgers club he was set to face Thursday night. It’s unclear if he felt the injury that night or perhaps during a bullpen session in between then and now.

Regardless of how or when it happened, the Cubs will now have to play without Taillon for however long he’s out, which will be at least two weeks with this IL placement. The rotation has been a strength for the club in the early going this year, as their collective 2.66 ERA ranks third among all major league clubs, helping them jump out to an 11-6 start. Marcus Stroman and Justin Steele have excellent ERA figures of 0.75 and 1.44, respectively, while Drew Smyly and Hayden Wesneski have decent marks of 4.70 and 4.15.

Those four will now be joined by Assad for the time being. He posted a strong 2.66 ERA in the minors last year between Double-A and Triple-A, helping him make his major league debut. Between last year and this year, he has a 4.07 ERA in 42 major league innings thus far. He’ll look to bring some of that minor league success to the bigs and keep the Chicago rotation in good shape, at least until one of Taillon or Kyle Hendricks is able to return.
