Mike Moustakas homered, Billy Butler and Brayan Pena each drove in a pair of runs and the Kansas City Royals kept Texas' potent offense in check for a second straight game in a 7-4 win over the Rangers on Tuesday night.
The Royals took advantage of two throwing errors by Rangers starter Colby Lewis (3-3) to score five unearned runs in the first two innings.
Moustakas reached base for a 22nd consecutive game to help make a winner of Vin Mazzaro, who made his first start this season. Mazzaro allowed three runs on seven hits in five innings. He struck out two and walked one.
Major league home run leader Josh Hamilton extended his hitting streak to 15 games with a single and added a sacrifice fly.
Reliever Tim Collins struck out five of the six batters he faced in the sixth and seventh innings for the Royals, who swept the two-game series and sent Lewis to his third loss in May.
Lewis' throwing error on a comebacker to the mound by Eric Hosmer put runners on second and third with no outs in the first. Jarrod Dyson scored on Butler's fielder's choice and Lewis retired Alex Gordon on a flyout to left field before Jeff Francoeur doubled and Moustakas was hit by a pitch. Pena followed with a two-run single to put the Royals up 3-0.
Moustakas came around to score on Chris Getz's run-scoring base hit.
Kansas City sent nine hitters to the plate in the inning.
Dyson led off the second with a single and advanced to second when Lewis bounced a pickoff attempt short and wide of the bag. Butler hit a double to score Dyson and put Kansas City ahead 5-0.
The run support was plenty for Mazzaro and the bullpen, which held the majors' top-scoring team to one run in four innings. Mazzaro had made six starts with Triple-A Omaha this season, going 1-0 with a 4.37 ERA. Before his promotion May 8, Mazzaro had allowed just two runs on eight hits in 13 innings in his last two starts.
David Murphy and Mitch Moreland had RBIs for the Rangers and Brandon Snyder homered in the ninth.
Dyson reached base three times for Kansas City, including a double to lead off the game.
