Anaheim, Calif. ? Aaron Guiel hit a two-run homer and Darrell May pitched seven innings Tuesday night, helping the Kansas City Royals beat the Anaheim Angels, 4-0.

Winning his third decision in a row for the first time in his career, May held the Angels to four hits and walked two. He struck out three.

May (3-4) pitched a complete-game, 8-2 victory against Cleveland in his last start. Before beginning his three-game win streak, he had gone 16 starts and 19 appearances without a victory.

Jason Grimsley pitched a 1-2-3 eighth, and D.J. Carrasco was perfect in the ninth as the AL Central-leading Royals won for the sixth time in seven games.

Guiel hit his third homer of the year, a two-out shot off John Lackey, to put the Royals up 4-0 in the fifth inning.

In the fourth, Michael Tucker ended Lackey’s 22-inning shutout string with a bloop single that scored two.

Lackey (6-8) allowed four runs on six hits in seven innings. He also was coming off a complete game — a 5-0 victory over Texas that was his first career shutout.

Guiel homered just over the wall in center, one out after Brent Mayne singled.

An inning earlier, Desi Relaford led off with a single. Two outs later, Ken Harvey doubled to right-center. Darin Erstad fielded the ball off the wall, whirled and threw to Chone Figgins, and Relaford was held at third.

But Tucker followed with a bloop to left-center that barely cleared the glove of shortstop Benji Gil as he sprinted toward the outfield. Both runners scored easily for a 2-0 lead.

The Angels got a runner as far as second with two out in each of the first two innings. But Shawn Wooten lined out to first to end the first, and May struck out Eric Owens to end the second.

The Royals increased their AL Central Division lead over the Minnesota Twins to 41/2 games. The Twins, who lost 8-6 Tuesday to the Texas Rangers, have gone 1-6 in July.

The Royals, on the other hand, have won six of seven games this month, and have scored an AL-high 40 runs, three more than Boston.

Notes: Anaheim SS David Eckstein, who hurt his right arm and shoulder Sunday when he tripped over LF Garret Anderson making a catch in short left field at Oakland, remains day-to-day and did not play. … The Royals are 6-1 in July and have scored an AL-high 40 runs in the month. … RHP Mike MacDougal, the Royals’ closer, is only the second rookie in club history to make the All-Star team. Kevin Seitzer was picked in 1987. MacDougal is second in the American League with 24 saves, trailing just Texas closer Ugueth Urbina. … Anaheim RF Tim Salmon, playing despite kidney stones, was in the lineup at DH.
