A's James Kaprielian undergoes season-ending shoulder surgery

Athletics right-hander James Kaprielian underwent successful right shoulder arthroscopic surgery Wednesday with Dr. Neal ElAttrache in Los Angeles to repair his posterior labrum, per a club announcement relayed by Martín Gallegos of MLB.com. There’s no timetable for a return but Kaprielian will miss the remainder of the season.

It’s yet another injury setback Kaprielian, 29, who has had more than his share. A first round pick of the Yankees back in the 2015 draft, he required Tommy John surgery in 2017. He was flipped to the A’s a few months later but didn’t make his debut in the Athletics’ system until 2019. 

He seemed to finally be on a good track in recent years, as he tossed 253 1/3 major league innings over 2021 and 2022. He still made a few trips to the IL but took on a decent workload and posted a 4.16 ERA in that time.

But he’s dealt with a series of setbacks since then. He required shoulder surgery in December of last year and then was rocked for 23 earned runs in 16 innings through his first six outings in 2023. He’s since been optioned and recalled a few times with slightly better results, though he landed on the IL at the end of June due to a shoulder strain. 

He’ll now miss the remainder of the season, with updates likely to come on his future status. He’ll be transferred to the 60-day IL whenever the club needs his roster spot.

He came into this season with his service time clock at 2.004. He spent enough time on optional assignment that he’ll come up just shy of the three-year mark but will still be eligible for arbitration this winter as a Super Two player, though the A’s are probably not guaranteed to tender him a contract. 

Although he’s a former first-round pick and one of the most seasoned pitchers on the roster, his constant health issues will likely give them pause. They will have the next few months to assess his progress before making that decision in the offseason.
