Espinosa is working his way back from a fractured right wrist and was scheduled to play just three innings in his first rehab appearance.

Espinosa, who has resumed baseball activities as expected, is on the disabled list with a fractured right wrist. He could remain in the minors to work on his swing once the rehab assignment officially ends.

"From my understanding, the break and the little chip that’s separated from it is not in a position where it can cause any more irritation," manager Davey Johnson said Saturday, without putting a specific timeline on Espinosa's resumption of activities. "And the major bone has probably had enough time to calm down. So hopefully he won’t have a whole lot of discomfort, no weakness in the hand. He was playing through it pretty good.”

Johnson also reiterated that Espinosa's torn rotator cuff is not a concern, and will not have any impact on when he can return from the disabled list. The wrist remains his only concern, after he opted to avoid surgery on the shoulder.

"The shoulder, he did a lot of exercising to strengthen all the muscles around the rotator cuff," Johnson said. "The doctors decided to go that route instead. Maybe we’re past it. I don’t know. That will be something we have to look at in the offseason."

Espinosa may not return to the majors when he comes off the disabled list. 

While the team did not go into much detail, MLB.com described it as just "a little injury," indicating that it has healed well without surgery.

Espinosa is expected to resume baseball activities in four to five days after having a cortisone shot in his wrist.
