Rollins was recalled from Triple-A Tacoma on Sunday, MLB.com reports.
EDGE Analysis
Rollins struggled during his nine appearances with the Mariners earlier this season, putting up a 7.04 ERA and 2.22 WHIP across 7.2 innings. Given his lack of prior success at the MLB level, Rollins will likely be limited to low-leverage duty out of the bullpen throughout September.
