Alex Rodriguez homered for the fifth straight game, connecting for the seventh time during that span and sending the Yankees beat the Royals 6-3 on Sunday for a three-game sweep.

Chien-Ming Wang earned his 18th win to remain tied for the major league lead, and Jorge Posada hit a tiebreaking, two-run double that helped New York extend its AL wild-card lead to four games over Detroit.
