Brendan Donovan (groin) has progressed to on-field running.
It’s typically the final step before a position player heads out on a minor league rehab assignment. The Mariners could certainly use Donovan back given their injury issues up and down the roster. The 29-year-old infielder has been battling lingering groin issues pretty much all season, which he believes are tied to last year’s sports hernia surgery. He’s been on the injured list since mid-May due to a groin strain.
