KANSAS CITY, Mo., Sept. 1 (UPI) -- Joe Mauer blasted a grand slam to hand Minnesota a big lead Saturday, but the Twins had to hang on to post an 8-7 win and doubleheader sweep of Kansas City.

Mauer's bases-loaded blast -- the first by a Twin this season -- came in the second inning and put Minnesota ahead 8-2.

Chris Parmalee had cracked a three-run shot in the first inning.

But Minnesota starter Liam Hendricks surrendered five runs (three earned) on 10 hits in just 3 2/3 innings and had to be lifted in favor of Anthony Swarzak (3-4), who registered the win despite yielding two runs over 2 2/3 frames.

The Twins bullpen closed the door after that, however, blanking the Royals over the final 2 2/3 innings with Glen Perkins firing a 1-2-3 ninth for his 10th save.

Perkins also saved the first game of the doubleheader, which the Twins won 3-1.

Royals starter Luke Hochevar (7-13) was rocked for eight runs on six hits, lasting just 1 2/3 innings.

Salvador Perez went 4-for-5 with an RBI while Billy Butler added three hits, including an RBI single, for Kansas City.
