When was the last time the Twins had a bench clearing brawl on the field? I was reading about the Boswell/Billy Martin fight in 1969 in which Boswell received stitches in his face from his manager outside a bar.

When Delmon Young went after Jose Mijares.

The last one that I can recall was in 1999 in Toronto when Paul Spoljaric threw at Cristian Guzman's head: http://articles.latimes.com/1999/sep/01/sports/sp-5746 I have seen a few bench-clearing "altercations" since then without real punches thrown. The Torii Hunter debacle in Cleveland 10 years ago (throwing the ball at the pitcher) jumps to mind as another possibility but I don't seem to remember it going much further than that.

There was one back in '78 between the Angels and Twins, too. In my mind I always thought there was one between the Twins and White Sox a few years back when they always seemed to be competing for the division. I think my mind is playing tricks on me though, probably just a couple of pitchers tossed for throwing at/near batters.

I think there was one in 1987 where Sal Butera got knocked out but I forget who it was with

I think they had one in Milwaukee in 87.
