Bauer gave up a go-ahead, two-run single before his temper tantrum at Kauffman Stadium in Kansas City.
Indians pitcher Trevor Bauer is known as one of the most intense players in baseball, and his fiery personality was on full display during his start against the Royals on Sunday.
Bauer allowed a go-ahead two-run single in the fifth inning, then flung a baseball over the center field fence at Kauffman Stadium in Kansas City before being pulled from the game.
Bauer's moment of frustration did not go over well with Cleveland manager Terry Francona. The two-time World Series champ had some choice words for his team's ace as he approached the mound.
Bauer apologized for the incident postgame.
"I owe a sincere apology to all my teammates, my coaching staff, the organization and all of our fans for how I conducted myself today" Bauer said. "It's unbecoming. It was childish, unprofessional. There's no place for it in the game."
Sunday's outing marked a key game for Bauer and the Indians. Cleveland entered the contest one game behind the Twins for first place in the AL Central.
Bauer has been the subject of trade rumors as July 31 approaches, and will be a free agent after the 2020 season. Sunday's toss could be his final moment in an Indians uniform,
