There are a number of injured Orioles who fans and the team have been hoping to see make a return in September. On Wednesday evening, we found out one name who won’t be back by season’s end. The team announced that injured infielder Jorge Mateo has had ulnar collateral ligament reconstruction, with an internal brace and flexor repair, on his non-throwing elbow. His season is over.
Any surgery on the UCL is in the vicinity of Tommy John surgery, although the announcement didn’t describe it as exactly that. Mateo suffered the injury in what looked like - and turned out to be - a grotesque collision with Gunnar Henderson while trying to field a ground ball during a July 23 loss to the Marlins.
