KANSAS CITY, Mo. – Mike Sweeney’s double with two outs in the bottom of the ninth inning scored Aaron Guiel, giving the Kansas City Royals a 5-4 victory over the Detroit Tigers in the first game of a doubleheader.

Guiel had a pinch-hit single with one out off Craig Dingman (3-3) and scored easily on Sweeney’s double to right-center, his second RBI of the game.

Mike MacDougal (4-5) pitched a scoreless inning for the win.

The Royals took advantage of errors by Chris Shelton and Nook Logan to score three runs, two unearned, in the first inning. Chip Ambres led off and reached first on Shelton’s fielding miscue at first base. Ambres advanced to third on Terrence Long’s single and scored on Sweeney’s sacrifice fly.

Emil Brown singled, sending Long to third. Brown went to second on Logan’s throwing error from center field. Matt Stairs lined a single to left to score Brown and Long.

The Tigers countered with two runs in the second. Brandon Inge and John McDonald each drove in a run.

John Buck’s sacrifice fly in the fourth scored Stairs, who led off with a walk and went to third on Angel Berroa’s double.

The Tigers tied it at 4 with a two-run fifth and chased rookie left-hander J.P. Howell. Curtis Granderson, Placido Polanco and Shelton started the inning with singles to produce a run, and Shawn Camp replaced Howell. Camp’s wild pitch allowed Polanco to score the second run of the inning.

Howell, who gave up four runs, six hits and three walks in four innings, has allowed 10 runs and 13 hits in seven innings in his past two starts, both no-decisions.

Camp pitched three shutout innings, allowing two hits, before being replaced by rookie left-hander Andrew Sisco to begin the eighth.

Tigers starter Mike Maroth went seven innings, allowing four runs, two earned, and eight hits. Chris Spurling replaced him in the eighth.

Notes: DH Dmitri Young was not in the Tigers’ starting lineup for the 13th straight game because of a left hamstring injury. He is limited to pinch-hitting duties and singled in the ninth, hitting for SS McDonald. When Young gets on base, a pinch-runner must be used. … RHP Jason Grilli made his Tigers debut in relief. It was exactly 30 years ago that Grilli’s dad, Steve, made his Detroit debut. … Ambres batted leadoff for the 10th time this season. … Detroit’s Ivan Rodriguez caught his 1,806th game, tying Rick Ferrell for ninth in big league history.
