Pirates win 4th straight, sweep Royals

PITTSBURGH (AP)   Andrew McCutchen homered and drove in three runs, A.J. Burnett won his fifth consecutive start and the Pittsburgh Pirates finished their first sweep of an AL team in more than a decade by beating the Kansas City Royals 3-2 Sunday.  McCutchen hit an RBI double in the first inning and hit a two-run homer in the third, giving Burnett (6-2) and three relievers enough support for Pittsburgh to win its fourth in a row.  This was the 50th interleague series the Pirates had played since taking three in a row from the Cleveland Indians June 15-17, 2001.  Pittsburgh is now tied for first-place with the Cincinnati Reds in the NL Central.  Alex Gordon and Alicedes Escobar each had two hits for the Royals, who have lost four in a row and six of eight.  Since May 25, the Pirates have the best record in the majors at 12-3.
