MINNEAPOLIS - Erik Kratz homered twice after replacing an ailing Salvador Perez, and Jason Vargas pitched seven strong innings to lead the first-place Kansas City Royals to a 6-4 victory over the Minnesota Twins on Monday night.
Vargas (10-5) allowed one run on four this and struck out three, but had his scoreless innings streak snapped at 17 when Oswaldo Arcia hit a solo homer in the seventh. Perez had two hits and two RBIs before leaving in the seventh because of discomfort in his right knee, helping the Royals win for the 21st time in 26 games.
Kansas City extended its lead over the idle Detroit Tigers in the AL Central to two games.
Trevor May (0-2) gave up three runs on seven hits and walked four in 4 2-3 innings for the Twins.
