Strikeforce: Rousey vs. Kaufman is in the books and once again Ronda Rousey has pulled off a first-round submission via armbar. Rousey came out striking in order to push Kaufman up against the cage, where the champion took the fight ot the ground as planned with a Judo takedown. From there, she went to her bread and butter, and it was only a matter of time before Kaufman submitted to Rousey’s signature move.

In other action, Ronaldo “Jacare” Souza defeated Derek Brunson with a vicious right hand and some ground-and-pound, making a case for a rematch with Strikeforce Middleweight champion Luke Rockhold. Tarec Saffedine outmatched Roger Bowling in a unanimous decision. With the win, Saffedine may find himself in a title fight with Nathan Marquardt. Anthony Smith pulled off an impressive triangle choke over Lumumba Sayers. Ovince St. Preux threw a heavy right hand that completely knocked his opponent T.J. Cook out cold in the third round.

Once again, Ronda Rousey has won in impressive fashion. The hype would seem to have some substance to it. She defeated a former champion in only 54 seconds, and subsequently called out suspended Cyborg Santos for a match. Santos could possibly be her only competition in WMMA. With the win, Rousey quiets those who still doubted her.
