On Saturday night, Ronda Rousey went from a star to a super-star. She defended her women’s bantamweight championship against Sarah Kaufman in the main event of Strikeforce: Rousey vs. Kaufman in 0:54 by what else… her signature armbar. Rousey almost immediately clinched with Kaufman and took the fight to the ground. She then locked up the arm and secured the armbar, forcing Kaufman to tap.
