The Twins optioned Duffey to Triple-A Rochester on Wednesday. Duffey was unlikely to be available for Wednesday's series finale with the Astros after he worked 1.1 innings in relief Tuesday and gave up four unearned runs on two hits and a walk. As a result, the Twins will swap him off the roster in exchange for a fresher bullpen arm in Fernando Romero.
Duffey threw two scoreless innings with three strikeouts in Thursday's loss to Toronto. Duffey has worked with new Twins pitching coach Wes Johnson to throw higher in the strike zone and quit using his sinker, the Minneapolis Star Tribune reports. The Twins and Johnson have changed the team's philosophy, with pitchers throwing strikes higher in the strike zone, and Duffey may benefit as he had six scoreless innings at Triple-A with 11 strikeouts before he as called up before Tuesday's game. Duffey could provide the Twins with a much needed boost in middle relief, while high-leverage opportunities can be had if he has success.
Duffey was recalled from Triple-A Rochester on Tuesday. Duffey has allowed one run while striking out 11 in six innings for Rochester this season. He hasn't had nearly that sort of success in parts of four big-league seasons, posting a 5.46 ERA and a mediocre 20.2 percent strikeout rate. Andrew Vazquez was optioned to Rochester in a corresponding move.
Duffey was optioned to Triple-A Rochester on Saturday. Duffey spent more time in the minors than the majors last season as he appears to be out of Minnesota's long-term plans despite stretches of being productive as a reliever in 2017. With a minor-league option left, he's likely to be shuttled up and down from Triple-A.
Duffey threw a scoreless inning with a strikeout in his first spring appearance in Saturday's split squad loss to Baltimore. Duffey is likely on the outside looking in for a spot in Minnesota's bullpen, especially since he has a minor-league option left. He's likely a candidate to provide depth and be shuttled up and down from Triple-A.
