Keuchel rips trolling fan after mean tweet

Dallas Keuchel's fastball velocity is down from where it was a year ago, but that's not stopping the Houston Astros lefty from throwing heaters at trolls on social media.

Less than 24 hours after pitching one of his best games of the season, the reigning AL Cy Young winner dropped the mic on a Twitter user who didn't appreciate the pitcher weighing in on the Cavaliers' title-clinching win.

Keuchel tossed seven strong innings Saturday to help the Astros defeat the Reds 5-4, and snap a string of three straight personal losses. Despite the outing, Keuchel's ERA remains at a career-high 5.32, while his average fastball speed is sitting under 90 mph for the first time since 2012.

"I'm a competitor, so yeah I'm going to be frustrated with not getting the win but team wins are ultimately more important," said Keuchel, who didn't factor into the decision during Saturday's extra-inning win.
