Three games into Friday's one-sided U.S. Open semifinal between Serena Williams and Sara Errani, CBS analyst John McEnroe figured the outcome was already a foregone conclusion.

McEnroe began evaluating Williams' chances in Saturday's final against top-seeded Victoria Azarenka, noting that he did not expect tentativeness to be a problem for the American star.

A 3-0 first-set lead is typically far too early to pencil any player into the next round, but it's hard to blame McEnroe because of the dominance Williams has displayed in New York the past 10 days. She has steamrolled opponents with astonishing ease, a streak that continued Friday with a 6-1, 6-2 victory over an overmatched Errani.

Even though Williams is a year older than Kim Clijsters when she retired last week and just a few months younger than Andy Roddick when he played his last match Wednesday, the 30-year-old American remains the most dominant force in women's tennis. She won Wimbledon, captured gold at the Olympics and stands one victory away from her 15th grand slam singles title.

Rather than waste words trying to sum up Williams' dominance, it's easier to allow some numbers to do it. Here's a by the numbers look at how untouchable Williams has been so far during the U.S. Open.
