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.
Duke recorded his fifth hold in Thursday's 5-2 win over the Giants, getting one out in the ninth inning. Duke was part of the three-pitcher attack manager Mike Matheny opted to deploy in the ninth inning, as he disposed of Jarrett Parker to get the second out with Brandon Crawford on second. It was the fifth consecutive scoreless effort for the veteran southpaw, who yielded runs in only two of 13 August appearances. The 34-year-old continues to see a brisk workload and has lowered his ERA from 6.75 to 5.59 over the aforementioned scoreless streak.
Duke (0-1) allowed an earned run on a walk and also recorded a strikeout over one-third of an inning in Wednesday's 5-4 loss to the Red Sox. He was also credited with his fourth hold. The run that Chris Young scored on Mookie Betts' game-winning double off of John Brebbia went on Duke's ledger, snapping his six-appearance scoreless streak. The veteran lefty has been impressive despite Wednesday's stumble, amassing all four of his holds over the last six outings. However, considering the mileage on his arm and the fact that he's less than a year removed from Tommy John surgery, it remains to be seen how frequent a workload he'll see during the balance of the campaign.
