Everyone loves an underdog. David vs. Goliath. Or in this case, Roberta vs. Serena. With a seemingly watered down women's side of the United States Open, Serena Williams seemed poised to make history by winning all four Grand Slams in a single year. Champion of the Australian Open, French Open, and The Championships (known as Wimbledon) and completely dominating, enter Roberta Vinci. The diminutive Italian went toe to toe with Williams and won. On American soil. Oddsmakers had the match at 300:1, this was a Miracle on Ice or Buster Douglas type upset. Maybe more. Roberta Vinci is 5'4" and 32 years old. She's never made it out of the fourth round of singles (she is a top notch doubles player). But 2-6, 6-4, 6-4, she stood among giants and captured youth. Our Sportswoman of the Week!
