The Texas Rangers won a fiery affair against the Toronto Blue Jays 7-6 as tension from last post-season reared its head once again with a pair of bench-cleaning incidents on Sunday.
Toronto had a 6-4 lead until Ian Desmond blasted a three-run homer over left field in the seventh, which came before emotion spilled over in the eighth.
Jose Bautista was hit by a pitch at the top of the eighth, before he slid in hard on second baseman Rougned Odor, who then punched the Blue Jays star which kicked off a melee in game that ended with eight rejections.
It was equally eventful - if not as violent - in New York where the Yankees won their second straight match against the Chicago White Sox 7-5, while the Oakland Athletics enjoyed a 7-6 win at the Tampa Bay Rays.
Eugenio Suarez went deep for the Cincinnati Reds with his three-run effort crucial to their 9-4 win over the Philadelphia Phillies, the Detroit Tigers managed a 6-5 victory against the Baltimore Orioles and the Miami Marlins saw off the Washington Nationals 5-1.
The Boston Red Sox won a see-sawing game against the Houston Astros 10-9, the Milwaukee Brewers accounted for the San Diego Padres 3-2 and the Pittsburgh Pirates upset the Chicago Cubs 2-1.
The Los Angeles Angels shut out the Seattle Mariners 3-0, as the New York Mets were knocked off 4-3 by the Colorado Rockies for the sweep.
Elsewhere, the San Francisco Giants beat the Arizona Diamondbacks 2-1 and the St Louis Cardinals beat the Los Angeles Dodgers 5-2.
Athletics third baseman Danny Valencia went three-for-five with three home runs and five RBIs in a win against the Rays. Valencia has been a bit of a journeyman throughout his career, but he may find a permanent home in Oakland after recording his first career three home-run game.
