Duke (4-4) struck out the only batter he faced to grab his first victory in a Mariners uniform Sunday against the Blue Jays. A quick five pitches was all it took for Duke to dispose of the pinch-hitting Teoscar Hernandez to end the seventh. He was subsequently rewarded with his first victory in his new digs when Nelson Cruz snapped a 3-3 tie in the home half of the frame with a two-run home run. Duke has been put right to work by manager Scott Servais, with Sunday serving as his third appearance in the six days he's been with the club. He's expected to see plenty of matchup-based assignments in the middle-to-late innings as warranted.
Duke was traded to the Mariners in exchange for Chase De Jong and Ryan Costello on Monday, Jon Heyman of Fancred reports. Duke will join the Mariners' bullpen after putting up a 3.62 ERA and 1.58 WHIP across 45 appearances with Minnesota this year. The left-hander has posted a career high 6.6 K/9 and has yet to allow a home run in 37.1 innings of relief. Look for him to be deployed primarily in low-leverage spots upon his arrival in Seattle.
Duke didn't give up a run in a third of an inning in Wednesday's win over Houston to earn his second hold of the season. He did walk two batters and had a strikeout. Duke has struggled a bit with six walks and an 11.25 ERA in four innings this season, but he's still being used in high-leverage spots and has eight strikeouts. He's being used as the primary lefty setup man in the bullpen.
Duke did not give up a run in an inning Sunday to finish spring training with 7.2 scoreless innings. Duke had five strikeouts and three walks in his 7.2 innings this spring. He'll serve as a setup man in the bullpen and could bypass Taylor Rogers as the primary lefty with Rogers struggling a bit this spring (7.15 ERA).
Duke has agreed to a contract with Minnesota, pending a physical, the Minneapolis Star Tribune reports. Duke had Tommy John surgery in October 2016, but returned in July. He had a 3.93 ERA in 18.1 innings. He had just a 5.9 K/9, however, with a 5.33 FIP. The Twins likely saw enough to think he'll improve in his first full season back from Tommy John surgery. He could figure prominently in the team's setup corps as a result.
