Strikeforce Video: Ronda Rousey Armbars Sarah Kaufman In 54 Seconds

Ronda Rousey was able to quickly and impressively defend her Strikeforce title last night with an armbar submission in only 54 seconds. Sarah Kaufman came into the fight as a considerable underdog, but I don't know that anyone expected it to be quite that easy for the champion.

The win was Rousey's sixth career victory, all by armbar. The most incredible thing is that, at 54 seconds, this was the second longest fight of Rousey's career.

Here are the ESPN video highlights for the bout:
