The Braves announced today that left-hander A.J. Minter has been placed on the 15-day injured list due to left hip inflammation. Fellow lefty Dylan Lee has been recalled from Triple-A Gwinnett in a corresponding move.
At this point, it’s unclear how serious Minter’s injury is or how long the club expects him to miss, but it’s perhaps noteworthy that this is his second IL stint for this issue this year. He landed on the IL due to left hip inflammation May 31, missing just over a month before being reinstated July 1. Per Justin Toscano of the Atlanta Journal-Constitution, Minter is still undergoing evaluation for his current status and the club isn’t sure if he’ll be able to return this season.
Despite the hip issue, he’s managed to post good results when on the mound, as he has thrown 34 1/3 innings with 2.62 earned runs allowed per nine. His 26.1% strikeout rate is a few ticks below his rate from the previous two seasons, but he’s also getting more ground balls.
There might be a bit of good luck in that ERA as he has a .222 batting average on balls in play and 94.2% strand rate, which are both on the fortunate side. But his 16.7% home run per fly ball ratio is essentially double his rate from the two preceding campaigns. FIP gives a pitcher blame/credit for home runs, so that metric has Minter at 4.46 this year, far worse than his ERA. But a metric like SIERA, which normalizes home run rate, is more kind and has Minter at 3.39. That’s still a noticeable gap from his ERA but it’s not far off from the 3.06 SIERA he had last year.
Regardless of how one feels about Minter’s stats this year, it’s a rough development for the Atlanta bullpen. The relief corps should still be in decent shape without him, as the club’s relievers have a collective 3.38 ERA on the year that trails only the Guardians and Brewers. But they’re in a place now where incremental differences might loom large. Their recent skid has dropped them to 61-56, barely clinging to the final National League Wild Card spot with the Mets just half a game back and several other teams within striking distance.
Manager Brian Snitker has been using Minter in key situations. Minter is second on the team in holds behind Joe Jiménez and his average leverage index is third behind Jiménez and closer Raisel Iglesias. Subtracting Minter will make it more challenging for Snitker to navigate the ends of tight games. Lee has strong numbers on the year, with a 2.00 ERA in 45 innings, but mostly in lower-leverage spots.
It also could be a rough development for Minter himself, as he’s an impending free agent. He has a strong career track record with a 3.28 ERA over his 384 appearances with a 29.3% strikeout rate, 8.6% walk rate and 39.9% ground ball rate. But he’s already had one IL stint of over a month this year and another lengthy absence could tamp down his offseason contract offers. He’ll celebrate his 31st birthday on September 2.
