Ronda Rousey keeps making history by defeating yet another opponent via armbar within the very first minute of the very first round. This time, she disposed of Sarah Kaufman to successfully defend her bantamweight championship in the main event of Strikeforce: "Rousey vs. Kaufman" last night (Sat., Aug. 18, 2012) at the Valley View Casino Center in San Diego, California. It took "Rowdy" just 54 seconds to take care of business, a feat that seems almost pedestrian thanks to her stellar track record. When fans expect you to destroy your opponent without breaking a sweat, you know we're talking about true greatness.
