The 35-year-old Greene, who went to an All-Star Game as the Tigers’ closer in 2019, has struggled to stay in the majors the last three years. Last season, he pitched twice for the Cubs in September, throwing three scoreless innings. He had a 1.84 ERA in 29 1/3 innings in Triple-A.

Greene was designated for assignment earlier in the month but returns to the big league squad for the final contest of the season. Greene posted a 1.75 ERA, 1.32 WHIP, and 27/12 K/BB ratio across 25 2/3 innings with Triple-A Iowa this season.

Greene was a prominent high-leverage reliever a few years ago, but he’s bounced around the last few years. The 34-year-old right-hander went unclaimed on waivers after being designated for assignment earlier this week. He’ll likely stick around with Chicago as emergency relief depth.

Greene pitched just once in his five days with the Cubs, throwing a scoreless inning Sunday. It’s the only major league appearance this season for the former Tigers closer.
