The Cubs are placing Jameson Taillon back on the 15-day injured list, manager Craig Counsell tells reporters (including Maddie Lee of The Chicago Sun-Times). Taillon departed his most recent start with left groin tightness. Javier Assad will be recalled from Triple-A Iowa to take his spot on the active roster.
Taillon just returned from a nearly two-month absence due to a right calf strain. This isn’t expected to be anywhere near as serious. Counsell said the Cubs believe it’ll be close to a minimal stint. They can backdate the placement to August 25, meaning he’ll be eligible to return on September 9. He’ll miss at least two turns through the rotation but should be back in plenty of time to vie for a spot on Chicago’s postseason roster.
The veteran righty has made 19 starts. Taillon carries a 4.15 ERA with a below-average 18.8% strikeout rate. He’s throwing plenty of strikes but has allowed home runs at a career-worst clip. This is is the fourth straight season in which Taillon has struggled to miss bats, and his velocity has trended down over the course of his four-year free agent deal.
Taillon looks like a fifth starter at this stage of his career. The Cubs will head into October with questions about their pitching depth. Cade Horton, Shota Imanaga and Matthew Boyd project as their top three arms for the playoff rotation as long as the Cubs don’t collapse in September. Assuming Michael Soroka will be limited to relief work if he’s able to make it back from a shoulder strain, Taillon and Colin Rea are the top options for a potential Game 4 postseason start.
Assad has lost most of the season to an oblique strain. He’s made three MLB starts since returning, allowing six runs across 14 innings. The Cubs have optioned him twice but recalled him shortly after on both occasions. Pitchers typically must spend 15 days on an optional assignment, but an exception is made if they’re replacing someone who goes on the injured list.
The Cubs have Horton and Imanaga to start the next two games. Assad will take the ball on Saturday at Coors Field. He’ll step into Taillon’s rotation spot for the time being. He’s a long shot to get much consideration for Chicago’s playoff roster — either in the rotation or long relief — but he should get at least two starts to try to make his case.
