Rollins was optioned to Triple-A Tacoma on Tuesday, Greg Johns of MLB.com reports.

EDGE Analysis

The M's added some bench depth with Shawn O'Malley (foot) banged up, promoting Dan Robertson and sending Rollins back to Tacoma. Rollins made three scoreless appearances during his most recent stint with the big club, but he did walk three over 2.2 innings. He's issued just one walk in 30.2 innings with Tacoma this season and figures to get another chance before too long.
