Rookie sensation Jasson Dominguez tore his UCL:

Aaron Boone said Dominguez reported soreness in the elbow as far back as his first series in Houston, but it didn’t impact him at the plate until he was taking batting practice Sunday. 

He is expected to be out for 9-10 months.

Bryce Harper showed hitters can come back from this injury quickly, and youth in on Dominguez’s side in this regard. Of course, the Yankees may not want him as a designated hitter, since they have plenty of people on that team better suited to that role. I could see him DH’ing in the minors until he can throw again, which may mean he might not be back with the Yankees until 2025.

Correction: I mistakenly typed 2024 in the original post.
