The main event of tonight's (Sat., Aug. 18, 2012) Strikeforce: "Rousey vs. Kaufman" event from the Valley View Casino Center in San Diego, California, featured Ronda Rousey defending her bantamweight championship for the first time against top contender Sarah Kaufman.

Rousey's rise to fame has been fast and furious, as she's collected arms while gaining notoriety for her no frills approach to fight promotion. Kaufman has been just the opposite, a soft spoken grinder with the striking game to halt the heavy hype surrounding the champion.

It just didn't go down that way.

Actually, it went exactly the way it always does.

50 seconds. Armbar. Tap. STILL women's bantamweight champion, Ronda Rousey. It really doesn't get any better than this as far as women fighting inside a cage.

After, she challenged Cristiane Justino to a fight at 135-pounds. "I'm the champ now, the champ doesn't go to you, you come to the champ," she said.

Rousey came out fast, looking to strike with just enough punches to get the clinch. Once she did, she got Kaufman to the floor and once that happened, it was over.

Immediately, she went for the armbar and there was just nothing Kaufman could do.

It took 54 seconds but it happened like it always does. Rousey by armbar.
