Grant Balfour is known for letting his emotions take over him on the baseball field. On Monday afternoon, the Oakland Athletics closer let it happen during his team’s most important game of 2013.

In the bottom of the ninth inning of Oakland’s Game Three matchup with the Detroit Tigers, the pitcher got into a heated exchange with designated hitter Victor Martinez. With the A’s up 6-3, the catcher led off the frame in attempt to mount a comeback. After a foul ball, the two began jawing at each other and had to be separated. Both benches cleared as Martinez approached the mound.

The censors for MLB Network were not quick enough to prevent the language from airing, as several expletives could be heard over the broadcast. Play-by-play broadcaster Matt Vasgersian apologized for the profanity.

Order was eventually restored and no ejections were handed out. Balfour didn't give up a run to help give Oakland a 2-1 ALDS lead.

In a postgame interview on the field, Balfour said that Martinez was "staring me down."

The 35-year-old Australian's nature is known as “Balfour Rage.” There is even a BalfourRage Twitter account with over 2,600 followers.
