The Mariners recalled Bernardino from Triple-A Tacoma on Tuesday.
Bernardino was returned to the minors just two days ago after serving as the Mariners' 27th man in Saturday's doubleheader with the Angels, but he'll be eligible to rejoin the big club since Seattle moved Ryan Borucki (forearm) to the 15-day injured list Tuesday. The Mariners are likely to reserve Bernardino's usage for lower-leverage spots or for lefty-heavy portions of opposing lineups.
