Royals closer Kelvin Herrera pitched a clean ninth to pick up his second save of the season.
Right-hander Nathan Karns held the Angels to one run over six innings, allowing just four singles, while walking two and striking out three in his second start of the season. Karns gave up a run in the first on an Albert Pujols groundout, but Karns blanked the Angels the rest of the way -- at one point retiring 12 in a row -- and departed with a 2-1 lead.
Angels right-hander Matt Shoemaker allowed two runs on five hits over 5 1/3 innings, with two walks and seven strikeouts in a 105-pitch effort.
