Gsellman signed a minor-league contract with the Cubs on Thursday that includes an invite to big-league spring training, Jesse Rogers of ESPN.com reports.
Gsellman recorded a 3.77 ERA with the Mets last season, but that came in just 28.2 innings as he was limited by a lat injury. It also came with a very low 14.3 percent strikeout rate. He'll compete for a spot in the Cubs' bullpen ahead of the 2022 campaign.
