Pinder (elbow) began a rehab assignment with short-season Staten Island on Tuesday, tossing three scoreless innings with five strikeouts.
Pinder underwent Tommy John surgery in April of 2016, but it seems like everything is back in working order. He'll likely require a few more rehab appearances before returning to full duty with the Triple-A squad, but this is certainly a good sign moving forward. He could be back in full sometime in early July.
