Putting in his bid for Knockout of The Night, Melvin Guillard knocked out Shane Roller in the first round at UFC 132 in Las Vegas, NV, Saturday.

Guillard looked confident and smooth, throwing a variety of kicks to a very stiff Roller. Guillard caught Roller with a left hook that dropped him and after getting back up, Guillard connected on a knee and followed it up with a straight left that flattened Roller. Three right hand hammer fists later and Roller was out cold with referee Josh Rosenthal calling the fight at 2:12.

Guillard (28-8-2-1) has won five straight and now has two straight wins by T/KO. The 28-year-old has been in the UFC since late-2005 and carries an 11-4 UFC mark.

After an eight-fight run in the WEC, Roller (10-4) made his UFC debut in March with a big KO win over Thiago Tavares. The 31-year-old went into Saturday on a two-fight win streak.
