US Open Tennis 2013 Results: Early Day 3 Scores and Highlights

Wins by No. 3 seed Agnieszka Radwanska and No. 5 seed Li Na highlighted the early action on Day 3 of the 2013 U.S. Open. Radwanska defeated Maria-Teresa Torro-Flor in straight sets, 6-0, 7-5. The latter put up a valiant effort in the second set, but Radwanska proved too strong for the 21-year-old Spaniard.

Radwanska will face 32nd-seeded Anastasia Pavlyuchenkova in the third round in what should be another win for Radwanska.

Li took care of Sofia Arvidsson, 6-2, 6-2. Li was still waiting on the winner of the Laura Robson-Caroline Garcia match to see whom she will face in the third round.

Here's a look at all the matches that were finished by 4 p.m. ET, followed by a look ahead to the night session.

Looking Ahead to the Night Session

Andy Murray Attempts to Take Steps Toward Repeat

After grabbing his first Grand Slam title at the 2012 U.S. Open, Murray has finished runner-up at the Australian Open and won Wimbledon this year. He's back and looking for the repeat, as well as pining to become the game's top-ranked player.

Michael Llodra of France stands in his immediate path on Wednesday night. Murray and Llodra have met three times before with Murray taking each match. Llodra has only captured a set in those matches and chances are he'll meet a swift end in this second-round clash.

Serena Williams Looking to Restore Her Dominance

An angry Williams is dangerous when she's focused. That looks to be the case as the world's best female player is trying to bounce back from disappointing performances at Wimbledon and the Western & Southern Open.

She is set to try to take out her frustrations on Galina Voskoboeva on Wednesday night. In one other prior meeting, Williams won in straight sets, 6-2, 6-3. Barring a complete collapse, Williams should handle Voskoboeva easily.

Which Top-10 Seed Has Best Chance to Be Upset?

If there is a top-10 player on either the men's or women's draw who seems ripe for an upset, it is Stanislas Wawrinka.

He takes on Radek Stepanek on Wednesday. To say Wawrinka has looked vulnerable lately is an understatement. A back injury forced him to retire from his quarterfinal match against Feliciano Lopez at the Swiss Open on July 26.

Wawrinka has struggled since Wimbledon when he was upset in the first round by Lleyton Hewitt. 

He hasn't made it past the second round of any tournament since he reached the final of the ATP Top Shelf Open in late June.

Stepanek has beaten Fabio Fognini and Nicolas Almagro in his last two tournaments. He could hand Wawrinka yet another disappointing loss.
