Oakland, Calif ? Alcides Escobar had three hits and two RBIs, Danny Duffy pitched six innings for his first major league win and the Kansas City Royals beat Oakland 7-4 on Tuesday night.

The victory, which improved the Royals to 30-37 on the season, spoiled the home debut of Athletics interim manager Bob Melvin.

The Royals, led by rookie third baseman Mike Moustakas, who singled twice and scored both times, and designated hitter Billy Butler, who added a two-run double, won for the fourth time in five games.

Kansas City improved to 3-1 on its current road trip following a 4-7 homestand.

Duffy (1-2), who began the season in the minors, gave up two runs and scattered four hits.

The rookie left-hander pitched out of jams with two runners on and less than two outs in three innings and overcame four walks to win for the first time in six starts.
