NEW YORK, NY, USA - The third round commences at Flushing Meadows on Friday, featuring a rematch of a Wimbledon quarterfinal.

Friday, Third Round

Arthur Ashe Stadium
[12] Belinda Bencic (SUI #12) vs. [23] Venus Williams (USA #23)
Head-to-head:
Williams leads 3-0
A WTA Rising Star meets a player in orbit for 17 years and counting at this year's US Open.

Belinda Bencic was facing down the barrel of triple match point against Misaki Doi on Wednesday night, but the young Swiss gamely turned things around to edge her Japanese opponent in three arduous sets. Dominant in her opening round, Bencic will need to be at her best to turn around a decidedly lopsided head-to-head in her next match.

Two-time US Open winner Venus Williams hasn't exactly sailed through either of her first two rounds, dropping second set tie-breaks to both WTA Rising Star Monica Puig and native New Yorker Irina Falconi. But the veteran has gotten things done when backed against a wall. The American has yet to drop a set to Bencic in three meetings, but the No.12 seed has been on an exponential rise since winning her first WTA title in Eastbourne, and made a thrilling debut on Arthur Ashe Stadium one year ago when she beat 2008 finalist Jelena Jankovic to reach her first Grand Slam quarterfinal.

Louis Armstrong Stadium
[19] Madison Keys (USA #19) vs. [15] Agnieszka Radwanska (POL #15)
Head-to-head:
Radwanska leads 4-0
A home favorite has the opportunity to make a big splash and reverse a bitter Wimbledon loss from two months ago.

No.19 seed Madison Keys has been in ruthless form to start her US Open campaign; the WTA Rising Star is into the third round of her home major for the first time in her career, and is undoubtedly looking to go one better as play closes on Louis Armstrong Stadium.

Keys played her next opponent in two of the last three Wimbledon Championships, falling in three sets each time. No.15 seed Agnieszka Radwanska turned her season around by beating Keys and then coming within games of a second Wimbledon final earlier in the summer, but has never progressed past the fourth round in Flushing.

A classic battle of offense versus defense will converge, as Keys - now coached by 1998 US Open champion Lindsay Davenport - will look to hone in her aggressive tendencies while Radwanska will try to absorb the easy power from her feisty challenger to match her career-best Open result.

Stat to watch: Keys has managed a +1 winners to unforced errors differential in her first two matches, straight set wins over unseeded Czechs, Klara Koukalova and Tereza Smitkova.
