Farrell signed a minor-league contract with the Cubs on Monday, Chris Hilburn-Trenkle of Baseball America reports.
Farrell spent the 2021 campaign with the Twins, finishing the year with a 4.74 ERA, 1.66 WHIP and a 25:13 K:BB across 24.2 frames (one start). Following Monday's signing, he'll likely head to Triple-A Iowa where he'll serve as bullpen depth.
