"I think it was the first save of my life to be honest," Duensing said.
Duensing tossed a scoreless 14th inning to preserve the Twins' one-run lead but did give up a two-out hit to Jean Segura before getting Ryan Braun to ground out to third to end the game. He also had some help from his defense as second baseman Brian Dozier snared a liner from Norichika Aoki for the second out.
"It was not easy," Duensing said. "Dozier made an unbelievable play, and I got Braun to roll the ball over somehow. I thought it was in his wheelhouse. But it all worked out."
Duensing, who has a 3.60 ERA in 20 innings this year, was given the game ball after the save and had it authenticated. He also received the lineup card from the game.
"I'm glad Brian was able to get the job done," Twins catcher Joe Mauer said. "He's been throwing the ball well for us all year. So it was a neat deal for him to get a save."
