Smith was diagnosed with a dislocated right pinky finger after exiting Sunday's game against the Phillies, Anthony DiComo of MLB.com reports.
Smith attempted to barehand a comebacker in the top of the seventh inning Sunday, and he immediately exited the game with a trainer. The right-hander's X-rays didn't reveal a fracture, and he's considered day-to-day ahead of Monday's series opener against the Nationals.
