Cardinals place inconsistent starter on injured list with back strain

St. Louis Cardinals starter Steven Matz

The Cardinals announced that left-hander Steven Matz has been placed on the 15-day injured list, retroactive to May 1, due to a lower-back strain. Right-hander Kyle Leahy was recalled in a corresponding move.

The Cards signed the southpaw to a four-year, $44M deal going into 2022 but they’ve gotten little return on that investment so far. Matz battled shoulder issues for much of 2022 and only tossed 48 innings with a 5.25 earned run average. Last year, he struggled out of the gate and got moved to the bullpen. He got in a good groove and retook a rotation spot as they played out the string on a lost season, finishing strong enough to have a 3.86 ERA by season’s end.

The club was surely hoping he could carry some momentum from that solid finish into 2024, and he did for a brief moment. After three starts, Matz had allowed just three earned runs and had a 1.80 ERA. But he’s allowed 16 earned runs in his three most recent outings, swelling his ERA to 6.18 for the year.

Per Katie Woo of The Athletic, an issue cropped up with Matz’s back after his April 23 outing. The club had an off-day on April 25 and then a rain-out April 29, which meant Matz got some extra rest before taking the ball again on April 30. It was hoped that the extra time would help him get beyond the back problem, but that didn’t come to pass. His velocity was down in that last start and he was pulled after allowing four earned runs in 3 1/3 innings. He was sent for an MRI Thursday, per Woo. and it seems the club has decided to put Matz on the shelf for at least a couple of weeks.

That will leave the club with Sonny Gray, Lance Lynn, Kyle Gibson and Miles Mikolas as healthy starters, but they will need a fifth at some point. As of Friday, the Cards are playing 13 games in a row before their next off-day.

Drew Rom was recently transferred to the 60-day injured list and won’t be an option. Matthew Liberatore could be considered but he’s been in the bullpen and isn’t stretched out. Zach Thompson was in the big league rotation before being being moved to the bullpen and then optioned to the minors. He tossed 3 2/3 innings in his most recent Triple-A start.

Sem Robberse and Adam Kloffenstein are each stretched out at Triple-A on on the 40-man, though Kloffenstein has a 5.93 ERA this year. Robberse is in much better form with a 1.77 ERA through six Triple-A starts, though he just started last night and likely wouldn’t be called up before Tuesday. Prospects Gordon Graceffo and Michael McGreevy are also stretched out in Triple-A, but neither is on the 40-man and they both have worse results than Robberse so far.
