KANSAS CITY -- Jose Berrios delivered a solid outing on Friday, but the Twins' bullpen couldn't finish what Berrios had started.
Closer Trevor Hildenberger entered the ninth with a one-run lead, but it all went astray for Minnesota when Whit Merrifield tied the game with an RBI single and Salvador Perez won it with a walk-off grand slam as Kansas City exploded for five runs in the 8-4 victory.
Hildenberger went to a 3-2 count on Perez and then tried to get Perez out in front with a slider.
