Andy Roddick Lives to Play Another Day
Roddick may have announced that the U.S. Open will be the last in his pro career, but that doesn't mean he's going to go down easily.
The seasoned veteran took the court against Bernard Tomic of Australia and coasted his way to the next round of his last-ever tournament. Roddick never surrendered a set in the contest, only having trouble in the second when the talented teenager would come within two games of the American.
With another win in the books for Roddick, he'll look to have similar results next round against Italy's Fabio Fognini.
Maria Sharapova Dominates Mallory Burdette
This isn't exactly a tournament surprise, as Sharapova holds the third seed in the tournament and faced an unranked opponent in Burdette. Still, the talented Russian tennis star did not fall victim to what would have been a major upset, winning 6-1 in both sets.
The whole match took 58 minutest to complete, which is similar to the pace that Sharapova was going in the French Open earlier this year where she won her first-ever tournament at Roland Garros.
Sharapova has only won the U.S. Open once in her career, but she has come one step closer to adding her second trophy after this victory.
Novak Djokovic Takes Care of Business
Djokovic did his best Sharapova impression against Dutra Silva on Day 5, defeating his Brazilian opponent by the score of 6-2, 6-1, 6-2 in just over 90 minutes of play.
Even with the box score indicating a breeze of a day for the Serbian, Djokovic did tell BBC it was harder than it looked, explaining:
I didn't know much about my opponent; I'd never seen him play. Even if the scoreline doesn't indicate it, it was a tough match. I played well from the start to the end.
Djokovic is the defending U.S. Open champion and he's making sure everyone else in the field remembers that, using dominant play like this as a not-so-friendly reminder.
