Puk (groin) threw off a mound Friday, Christina De Nicola of MLB.com reports.

EDGE Analysis

Puk has been held back a bit by left adductor tightness but has been able to take some steps forward in his recovery. The left-hander should be cleared for games soon if he can avoid setbacks. Acquired from the Athletics last month, Puk is expected to be in the mix for saves as part of Miami's closer-by-committee this season.
