Georges St-Pierre vs. BJ Penn, March 4, 2006

BJ Penn was making his comback to UFC after spending over two years in rival MMA promotions. While Penn mercilessly pounded on St-Pierre in the first round, the Canadian fighter bounced back to capture the second and third rounds. It was a very tough one to call, but two of the three judges awarded the split decision to St-Pierre. 

This would be the young fighter's first major win on his way to complete UFC domination over the following years!
