Holy cow. 😬#AlwaysRoyal pic.twitter.com/TJDh6ynMOu— FOX Sports Kansas City (@FSKansasCity) July 28, 2019Trevor Bauer had a rough day pic.twitter.com/xjcem0BBsA— Brewers Dugout – Trey Supak Fanclub (@brewers_dugout) July 28, 2019Hey @statcast. Need exit velo and launch angle plz. pic.twitter.com/tuneoa9dTG— Jeff Passan (@JeffPassan) July 28, 2019Trevor Bauer, In-Game Long Toss. pic.twitter.com/ZJnWFE19fx— Rob Friedman (@PitchingNinja) July 28, 2019Bauer seemed to have some words with Francona on the mound, assumedly just clearing the air that he meant no disrespect by tossing the ball over the fence.Following the game, Bauer issued an apology and called his actions “childish and unprofessional,” but clarified his disappointment was only in himself, not in Francona for taking him out. If you like exit velocity and launch angle, Trevor Bauer is apparently your guy.Bauer has never been one to shy away from showing some emotion. The enigmatic Indians starter had a rough day at the office on Sunday, allowing seven runs on nine hits and four walks in 4 1/3 innings pitched vs. the Royals. It was a bad start, but Bauer’s worst toss of the day came just before manager Terry Francona pulled him from the game. Trevor Bauer opened with an apology before taking any questions after throwing a ball over the center-field wall out of frustration in today’s game: pic.twitter.com/FUMxILdGmd— Mandy Bell (@MandyBell02) July 28, 2019Bauer, the subject of trade rumors, has had a difficult time replicating the success of his 2018 season. Entering Sunday’s game, he was pitching to a 3.49 ERA in 23 starts, a full run higher than his 2018 ERA and has allowed 22 long balls on the season, three shy of tying his career high.Still, a team looking to add quality starting pitching would consider Bauer; he leads the majors in innings pitched and has consistently been a workhorse in his career.And if Sunday’s strange exit is any indicator, he’s still got plenty of juice in that arm.
