Boston The Boston Red Sox's four-game winning streak was history with one swing of Carlos Delgado's bat.
Delgado drilled Boston reliever Pete Schourek's first pitch of the ninth inning over the left-field wall Friday night to lead Toronto to a 4-3 victory.
"In that situation early in the count, I'm looking for a pitch I can drive," Delgado said. "I got a pitch out over the plate and I was able to drive it."
Raul Mondesi also homered, the 200th of his career, and Brad Fullmer and Darrin Fletcher had RBI singles in the seventh as Toronto beat Boston for just the second time in eight games.
Pedro Borbon (2-3) recorded one out to pick up the win, and Billy Koch pitched a perfect ninth for his 12th save.
Boston squandered a strong performance from starter Hideo Nomo, who struck out 12 in eight innings, allowing three runs on six hits.
Toronto received 72/3 strong innings from starter Esteban Loaiza, but he couldn't hold a 3-2 lead in the eighth when Boston's Jose Offerman drove in pinch-runner Shea Hillenbrand from third with a bloop single to tie the game at 3-all.
It looked like another comeback was in store for the Red Sox, who scored four runs in a freakish ninth inning to beat Tampa Bay 7-4 Thursday night.
But when Schourek replaced starter Hideo Nomo in the ninth, Delgado drove his first pitch to the opposite field for a solo home run.
Schourek knew his first pitch of the game was trouble the moment he let go of the ball.
"He should have hit it out," Schourek said. "It was a bad pitch. ... As soon as he started his swing I said, 'Uh-oh."'
Boston's lead over the New York Yankees in the AL East was cut to three games after the Yankees beat Tampa Bay 6-3.
Rangers 2, Athletics 1
Oakland, Calif. Doug Davis scattered seven hits over seven innings to help lead Texas over Oakland. Frank Catalanotto and Ivan Rodriguez each had two hits and drove in a run as the Rangers won their fourth straight in Oakland. Texas has won six of eight from the A's this season its best record against any team.
Davis (3-5), who stopped a career-high four-game losing streak, struck out a season-high six and walked one in winning for the first time since April 18.
Angels 8, Mariners 1
Seattle Jarrod Washburn allowed five hits in 72/3 innings and Anaheim scored six runs in the fifth inning to beat Seattle. Washburn (5-4) won his fourth straight decision as the Angels won for the second time in eight games against the Mariners this season. The Mariners (54-18) have the best record in the majors and lead the second-place Angels by 181/2 games in the AL West, despite dropping four of six games.
The Mariners, who were leading the league with an average of 6.3 runs per game coming into the game, were shut out until John Olerud's RBI single in the eighth.
Tigers 5, Twins 4
Detroit Robert Fick hit a leadoff homer in the eighth inning as Detroit overcame a four-run deficit. The Tigers have won three straight while the Twins have lost seven of eight and 11 of 15.
Detroit relievers Heath Murray, Willie Blair and Todd Jones kept the Tigers in the game with six innings of scoreless relief after starter Dave Mlicki allowed four runs on eight hits and two walks over three-plus innings. The Tigers trailed 4-0 after 31/2 innings before rallying to tie it with two runs in the fourth, one in the fifth and one in the seventh.
Orioles 6, White Sox 4
Baltimore David Segui snapped a tie with a two-run double in the seventh inning as Baltimore rallied to beat David Wells and Chicago. Jerry Hairston had three hits for the Orioles, who trailed 3-0 before scoring twice in the sixth and adding three runs in the seventh. Baltimore is now 2-24 when trailing after six innings.
Jose Canseco, playing in his second game with the White Sox, drove in three runs. But Chicago's four-game winning streak ended, and the White Sox (34-36) missed a chance to reach .500 for the first time since they were 4-4 on April 11.
Yankees 6, Devil Rays 3
St. Petersburg, Fla. Mike Mussina pitched seven solid innings and Shane Spencer homered and drove in three runs to help New York beat Tampa Bay. Mussina (7-7) weathered back-to-back homers by Aubrey Huff and Steve Cox in the fourth inning and allowed three runs and seven hits.
Spencer hit a two-run homer in the second and added a RBI double in the eighth. Paul O'Neill had a sacrifice fly in the fourth and Derek Jeter broke a 3-all tie with a run-scoring single in the fifth.
