The Twins recalled Rojas from Triple-A St. Paul on Thursday.
The 23-year-old rejoins the big club for the third time this season. Rojas has made six appearances (two starts) for the Twins, producing a 1.65 ERA, 1.53 WHIP and 18:13 K:BB across 16.1 innings. He's expected to serve as a multi-inning option out of the bullpen while he's up with Minnesota.
