KANSAS CITY, Mo. - Second-base umpire C.B. Bucknor called interference on a sliding Carlos Guillen in the ninth inning, nullifying the tying run and giving the Royals a 4-3 victory Tuesday night over the Tigers.
With Detroit trailing 4-3 and one out in the ninth, Ivan Rodriguez appeared to beat out a double play, allowing the tying run to score from third.
But right after first-base umpire Chuck Meriwether called Rodriguez safe on a close play, Bucknor called interference and an automatic double play.
Alex Sanchez would have scored the tying run if not for Bucknor's call on Guillen, who appeared to slide cleanly across the bag. The Tigers protested vigorously, to no avail.
Chris Shelton singled off Jeremy Affeldt leading off the ninth, went to third on a one-out double by Sanchez and made it 4-3 on Guillen's grounder to second baseman Desi Relaford, whose throw to first bounced in the dirt for an error.
Angel Berroa hit a tiebreaking triple in the seventh and Kansas City snapped a four-game losing streak.
Berroa, who was 2-for-3 and is batting .382 lifetime against the Tigers, connected off Mike Maroth after Detroit scored two in the top half to tie it at 2.
Maroth, whose 21 losses last season led the league, gave up two runs in the first, then held Kansas City scoreless until Matt Stairs singled leading off the seventh, was sacrificed to second and scored on Berroa's liner to left-center.
RED SOX 12, A'S 2: The first meeting between Boston and Oakland since last season's playoffs didn't provide much drama.
Mark Bellhorn homered and drove in five, and the host Red Sox backed Curt Schilling with their top offensive performance of the season.
Manny Ramirez hit his 12th homer and drove in three and David Ortiz had four hits and doubled twice to increase his league-leading total to 20. Bellhorn, Johnny Damon and Jason Varitek had three hits each.
Boston sent Tim Hudson to his shortest outing this season (four innings) and set season highs for runs and hits (19). The East leader won its fourth straight and ended Oakland's winning streak at five.
YANKEES 11, ORIOLES 3: Alex Rodriguez hit a three-run homer and Jon Lieber pitched seven innings of four-hit ball, leading visiting New York past Lee Mazzilli's slumping Orioles.
Facing the Yankees for the first time as a rookie manager, Mazzilli watched as his former team dealt Baltimore its season-high fifth straight loss. When Mazzilli served as first-base coach under manager Joe Torre from 2000-03, the Yankees were 46-22 against Baltimore.
New York has won 40 of its past 51 against the Orioles and is 56-27 at Camden Yards.
RANGERS 7, WHITE SOX 4: Kenny Rogers won his third straight start, tying for the major-league lead with his seventh win for visiting Texas. Rogers allowed two runs and seven hits in six innings, struck out six and walked one.
MARINERS 5, INDIANS 4 (12): Raul Ibanez hit a run-scoring single with two outs in the 12th as Seattle handed host Cleveland its season-high sixth straight loss. John Olerud had three hits, including a tying two-run double in the eighth for the Mariners.
