The Daytona 500 and UFC 157 are different in many ways, but both shared a female in the lead role in common.
The media couldn't get enough of Danica Patrick, the pole-sitter for the Daytona 500, as she looked to become just the second woman in the history of NASCAR to ever lead the race under non-caution circumstances. She accomplished that goal on Lap 90, when her GoDaddy.com car took over the top spot.
Like Patrick, the UFC's Ronda Rousey also made history on Saturday night when she became the first woman to ever win a fight in the Octagon, defeating Liz Carmouche in the first round of the bout. Her win solidified her place as the top female fighter in the sport.
With these women exuding plenty of "girl power" into their traditionally testosterone-filled sports, now seems like a good time to take a look at the 10 best female athletes in America today.
