ARLINGTON, Texas, May 15 (UPI) -- Brayan Pena highlighted a big first inning with a two-run single Tuesday and the Kansas City Royals went on to a 7-4 victory over Texas.

Pena's hit was sandwiched between RBI from Billy Butler and Chris Getz, giving the Royals a 4-0 lead against Rangers starter Colby Lewis (3-3), who hurt his own cause with a throwing error to open the floodgates.

Mike Moustakas socked a solo homer and Butler added a run-scoring double for Kansas City, which swept its two-game series at Arlington.

Vin Mazzaro (1-0) logged a victory in his first start of the season, holding the Rangers to three runs on seven hits over five innings.

Lewis lasted 5 2/3 frames, surrendering seven runs (two earned) on eight hits.

Brandon Snyder hit a solo homer for the American League West leaders, who lost for the third time in four games.
