Down Goes Another Russian: Oudin Beats No. 13 Petrova

17-year-old Oudin continues to dominate Russia, beating Nadia Petrova in the fourth round of the U.S. Open today to advance to the quarterfinals. It's her fourth straight upset of a Russian opponent. She struggled in the first set, losing 6-1, but came back to win the second in a tiebreak after being down a break. She won the third set 6-3.

The only person more thrilled about this than Oudin's family (specifically, her twin sister who was openly sobbing after the match) is CBS' Dick Enberg, who is now free to continue being old-man-creepy while calling her matches. The highlight from today: he said Oudin "looks like the kinda kid you wished lived next door." Decidedly more subtle than John McEnroe declaring her body "very physically mature" during her last match.

She needs to turn 18 before her next match to make all this commentary feel a little less, um ... illegal.
