Jason Kendall charged the mound and wrestled with Angels pitcher John Lackey, spicing up the Oakland Athletics' 10-3 win over Los Angeles on Tuesday.
The dugouts and bullpens emptied, followed by a lot of pushing and shoving. No one else was ejected because of the sixth-inning scuffle.
Eric Chavez hit a three-run drive for his 200th career home run and Bobby Crosby also hit a three-run homer for Oakland, which scored six runs in the ninth inning to break it open.
Lackey threw a pitch to Kendall that started out high and inside, then sharply broke back toward the plate. Kendall backed out of the batter's box, then suddenly charged the mound after Lackey barked something at him. The two grabbed each other as they both tumbled to the ground.
The Athletics were leading 3-1 and had the bases loaded with one out when the scuffle occurred. Brendan Donnelly replaced Lackey on the mound and Adam Melhuse finished Kendall's at-bat, beating the relay from second baseman Adam Kennedy on a potential double-play grounder to drive in Oakland's fourth run.
Brad Halsey (1-0), making a spot start for Rich Harden, allowed three runs and five hits in 5 1-3 innings to help the A's win their fifth straight game and finish their road trip 6-1.
Vladimir Guerrero chased Halsey in the sixth with his seventh homer, a two-run shot that narrowed the gap to 4-3.
Lackey (3-2) was charged with four runs and six hits in 5 1-3 innings and struck out six.
Indians 7, White Sox 1
At Cleveland, C.C. Sabathia made a strong return after injuring himself on opening night and Travis Hafner drove in four runs for the Indians.
Activated from the disabled list before the game, Sabathia helped stop Chicago's winning streak at four. The White Sox had won eight in a row at Jacobs Field.
Sabathia (1-0) allowed one run in five innings and got out of a bases-loaded jam in his first appearance since leaving the April 2 opener against Chicago with a strained oblique muscle.
Hafner, who hit a grand slam Monday night, hit a three-run homer in the first inning and added an RBI single as Cleveland stopped its three-game losing streak.
Mark Buehrle (3-2) gave up seven runs on 13 hits and three walks in 5 2-3 innings for Chicago.
Tigers 4, Royals 1
At Detroit, Brandon Inge and Craig Monroe homered and Mike Maroth pitched six strong innings to help the Tigers win their fifth straight game.
Detroit is 5-0 on its current homestand, having outscored the Minnesota Twins and Royals by a combined 40-4. Kansas City has lost five straight and is 0-11 on the road this season.
Maroth (4-1) allowed one run, four hits and a walk in six innings and lowered his ERA to 1.78. Three Detroit relievers finished, with Todd Jones pitching the ninth for his fifth save in as many tries.
Former Tiger Mark Redman (0-2) gave up three runs and five hits in 5 1-3 innings. He walked two and struck out one.
Orioles 9, Blue Jays 2
At Baltimore, Kris Benson took a shutout into the seventh inning to help the Orioles earn a split of the two-game series.
Jay Gibbons, Miguel Tejada and Ramon Hernandez homered, and Melvin Mora had three hits and two RBIs for Baltimore.
Benson (4-2) allowed two runs, six hits and two walks in 6 2-3 innings. It was the right-hander's second win over Toronto in six days. Todd Williams, the fourth Baltimore pitcher, got the final five outs for his first save.
