Detroit Tigers pitcher Max Scherzer has become the first to start 13-0 since 1986 following the Tigers' 6-2 victory over the Toronto Blue Jays on Wednesday night.
Scherzer pitched into the seventh inning to match the 27-year milestone, but the game was overshadowed by some unsavoury incidents on the diamond.
The Tigers fumed after the Blue Jays's Colby Rasmus ended Detroit second baseman Omar Infante's game with a hard slide in the fourth inning.
"We're really mad about that slide," said Scherzer. "That's a very dirty play in my book. When you watch it on replay, his spikes are up, he's sliding late."
Infante has been ruled out of Thursday's game, but x-rays after the win on Wednesday returned negative.
Still, Scherzer called for Rasmus to be suspended. The Blue Jays star slid late to stop a potential double play after a grounded hit by Rajai Davis.
Rasmus later denied the dirty play, and his manager John Gibbons refused to comment.
"I go hard every time," Rasmus told ESPN. "My intention is never to hurt anybody or nothing like that. I was taught that early in this game and that's how I play it.
"I didn't mean for nothing bad to happen. But it's no different than any time I ever come in."
Both benches then piled in and the bullpens emptied in the sixth inning after a high pitch by reliever Todd Redmond.
All the drama detracted from another win for Scherzer, who improved to 13 wins and no losses for the season. He allowed two runs and seven hits, struck out eight Blues Jays and walked just one in 6 and 1/3 innings.
The last pitcher to start 13-0 was Roger Clemens for the Boston Red Sox in 1986.
"It might not have been vintage Max but he was really good," said Tigers manager Jim Leyland.
