Yankees manager Aaron Boone said Thursday that Berti (calf) has been running at approximately 95 percent as well as hitting and throwing, MLB.com reports.

Berti is approaching a minor-league rehab assignment, which could begin shortly after the All-Star break. He's been on the injured list since May 25 as a result of a left calf strain. Berti will likely work as a utility man in a reserve role upon his return from the IL.
