He got up awkwardly from the play and put his shoulder back in place. As someone who once had a dislocated finger, and put it back, I can tell you this is not recommended. Here's what the play looked like:
Inge finished the game, but has not played since, and he and the A's Tuesday acknowledged the difficulty of playing baseball with a separated shoulder:
Donaldson has been playing third and catching at Sacramento, and he’s batting .335. I know manager Bob Melvin liked his effort level trying to get up to speed at third during the spring, and even though Donaldson has yet to hit at the big-league level, the A’s have always thought he might prove to be a decent utility-type player, considering that he can also play in the outfield.
While that may be, he'll never be as tough as Brandon Inge.
