Duran allowed a hit while striking out two over two-thirds of a scoreless ninth inning in Wednesday's 7-1 win over the Giants. He threw 104.6 mph and 104.4 mph fastballs, which are new Twins records, Do-Hyoung Park of MLB.com reports.
Duran was getting work in a blowout win as he hadn't pitched in four days. With the Twins off Thursday, Duran should be available for Friday's game against Toronto.
