KANSAS CITY, Mo. (AP) _ Jeff Reboulet drove in four runs, including a game-winning RBI single in the 10th inning, to lead the Kansas City Royals to a 6-5 win over the Pittsburgh Pirates on Friday night.

Reboulet hit a three-run double in the fourth, and Mike Sweeney added four hits, including his 13th homer, as Kansas City returned home from a nine-game road trip with a win.

The Royals, who have an AL-beat 18-7 record at home, just completed their first winning road trip of the season, going 5-4 in Boston, Pittsburgh and St. Louis.

They kept it up at home, despite blowing a 5-4 lead in the ninth. Brian Giles' second homer tied the game off Jerry Spradlin (2-0), who blew his third save in nine chances. The Royals have allowed a major league-leading 103 home runs.

Rey Sanchez doubled off Jason Christiansen (1-5) to lead off the 10th inning, and went to third on Johnny Damon's sacrifice bunt.

Reboulet followed with an opposite field line-drive single to give the Royals their 14th win in their last at-bat, including nine "walk-off" wins.

Giles hit a leadoff homer in the seventh off Jeff Suppan to cut Kansas City's lead to 5-3. It was the 19th home run allowed by Suppan, most in the AL. Suppan allowed three runs and six hits in seven innings.

Sweeney hit a solo homer in the first inning off Jason Schmidt to give Kansas City a 1-0 lead.

After the Pirates tied it in the third on Warren Morris' RBI double, the Royals scored four unearned runs in the fourth, with help from an error by first baseman Kevin Young.

Reboulet drove in three with a bases-loaded double and Sweeney followed with an RBI single.

Young, a native of Kansas City, Kan., hit his 100th career homer leading off the fifth inning.
