Pirates pitcher Dennis Santana tried to smack the hell out of a heckler during his game Thursday -- and the wild altercation was captured on video.
The reliever's outburst went down during the second game of the Pittsburgh vs. Detroit doubleheader ... after Santana says a man sitting near the Pirates' bullpen "crossed the line."
Footage shot by fans near the incident shows Santana pointing out the trash-talker to security, before he leaps up and attempts to hit the man in the face with an open left hand.
