Twins 10, Royals 8: Trevor Plouffe hit a pair of home runs, including the go-ahead blast in the five-run sixth inning, and Josh Willingham and Drew Butera also went deep as Minnesota set a Target Field record for home runs and rallied for its third win in two days to win the four-game series against visiting Kansas City.
The Twins had hit three homers in a game at Target Field seven times, including the second game of Saturday's doubleheader sweep.
The Royals seemingly took control with four runs in the top of the sixth — two of them coming on a play on which first baseman Justin Morneau and right fielder Darin Mastroianni both made errors.
But Minnesota came back with five in the bottom of the inning. Denard Span's sacrifice fly cut it to 5-2, Willingham followed with a three-run blast — his 17th — to tie it, and Plouffe put the Twins ahead with his team-leading 18th home run.
Butera added a three-run shot, his first, in the eighth inning.
Royals starter Bruce Chen (7-7) allowed three homers and was charged with the loss. He gave up six runs on six hits in 5 2/3 innings.
Jeff Gray (4-0) allowed two hits and a walk in one scoreless inning of relief for the win.
Irving Falu had three hits and four RBIs for the Royals, and Brayan Pena added two hits and two RBIs.
GAME NOTEBOOK: Minnesota has won 20 of its past 27 home games against Kansas City … The Twins have hit three home runs in back-to-back games and eight times in Target Field history … Minnesota's Joe Mauer went 1-for-4 to extend his hitting streak to 10 games … Twins starter Francisco Liriano allowed five runs (four earned) in 5 1/3 innings, failing to record a quality start for just the second time in seven starts since returning the rotation May 30.
