Justin Verlander was so pissed at Alex Cora during their game Tuesday night, he straight up told the Red Sox manager to "f*** off" ... and the heated dispute was all captured on a hot mic!!
The Astros ace had been dealing with some PitchCom issues during the second inning of Houston's tilt with Boston at Minute Maid Park ... and he needed a break from the action to get it all squared away.
But, when Cora thought he was taking advantage of the situation to avoid a pitch-clock violation .
