The Cubs acquired lefthander Andrew Chafin and a cash consideration from the Diamondbacks August 31 for a player to be named later or a cash consideration (it’s likely to be all-cash). At the time, he was on the injured list with a left finger sprain.
Saturday, the Cubs activated Chafin and placed righthander Rowan Wick on the 10-day injured list with a left oblique strain. With only nine days left in the regular season, Wick wouldn’t be able to return before the postseason, and oblique strains are notoriously difficult for recovery. The injury could end Wick’s season. It’s too bad, because he had been quite effective in recent outings. Over his last nine appearances Wick had a 1.08 ERA and 1.080 WHIP, with 11 strikeouts in 8⅓ innings.
Chafin had an 8.10 ERA in 11 outings with Arizona covering 6⅔ innings this year, with 10 strikeouts. He had one really bad outing vs. the Rangers in which he allowed three earned runs, otherwise he was fairly effective before being shut down with the injury. Prior to this year Chafin had been quite effective for Arizona between 2017 and 2019, posting a 3.46 ERA and 1.337 WHIP in 225 appearances covering 153⅓ innings, with a good K rate of 10.7 per nine innings.
Chafin will wear uniform No. 39 and be available for Saturday’s game against the Twins. This move gives the Cubs a bullpen with four lefthanders and six righthanders.
