Farrell will start Sunday's game against the Blue Jays, Phil Miller of the Minneapolis Star Tribune reports.
Farrell has a 1.31 ERA, 1.02 WHIP and 21:8 K:BB across 20.2 innings this season, and he'll make his first start of the campaign Sunday with the Twins employing a bullpen game. The 30-year-old covered a season-high 2.1 frames his last time out Monday and shouldn't be expected to go much deeper than that in Toronto.
