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 entered the day a game behind the first-place Cincinnati Reds in the NL Central. Alex Gordon and Alcides 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.
Burnett was charged with two runs on five hits and two walks with six strikeouts in 7 1-3 innings. Pittsburgh has won his past seven starts.
