Former top MLB prospect undergoes ulnar nerve transposition surgery

The Pirates informed reporters on Wednesday, including Alex Stumpf of MLB.com, that catcher/first baseman Endy Rodríguez has undergone ulnar nerve transposition surgery. Stumpf says Rodríguez is expected to be ready for spring training, so he seems to be done for 2025.

It’s another unfortunate twist for Rodríguez’s career. He was one of the top prospects in baseball ahead of his debut. When he got up to the show in 2023, he didn’t hit much, but his defensive grades were strong. Since he had been a good hitter throughout his minor league career, it was hoped he could be the club’s long-term catcher.

But going into 2024, he required surgery on his ulnar collateral ligament and flexor tendon, which wiped out that entire season. He got back on the field here in 2025 but this season has also been significantly marred by injuries. A laceration on his right index finger put him on the injured list in mid-April. He was reinstated from the IL in late May but was back on the shelf again about a week later due to elbow inflammation. He was pretty quickly transferred to the 60-day IL, suggesting the Pirates knew he was in for a long absence. Wednesday's news confirms that. Due to all those injury issues, Rodríguez only played 18 big league games this year. Since he missed all of 2024, it’s been close to two lost years.

That’s less than ideal for Rodríguez personally, but it also means the Bucs will go into 2026 with question marks behind the plate again. As of a few years ago, they had two of the top catching prospects in baseball. In addition to Rodríguez, they also had Henry Davis, taken first overall in 2021.

While Rodríguez has been mostly out of action, Davis hasn’t delivered on his promise. Davis currently has a .183/.271/.298 batting line in 579 big league plate appearances, including a .169/.247/.281 showing here in 2025. With Rodríguez out last year, the Bucs acquired Joey Bart in April. That looked like a masterstroke when Bart hit 13 home runs in just 282 plate appearances last year. But here in 2025, he has just two homers in 256 trips to the plate. His glovework isn’t highly rated, so the offensive drop-off hurts his value.

The Pirates have a great pitching staff but the lineup is lacking, with clear issues on the infield and behind the plate. Ideally, Rodríguez would have taken over the job this year and cemented himself as the man for the job. Instead, it’s more time rehabbing from surgery and more question marks.
