U.S. Open Match to Watch: Day 5

Two Americans will do battle under the lights.

Jack Sock vs. Andy Roddick

It may not be the best match on Friday's docket, but fans of American tennis, do miss this one!

Forgive Andy Roddick if he feels he is looking in the mirror heading into this match with the 18-year old , Sock.

Sock was born in Nebraska, same as Roddick, Sock possesses a big serve and a driving forehand, similar to Roddick's.  Sock is getting a chance to play a big match on the Stadium Court at the U.S. Open, much like Roddick did when he was younger.

Both players will be on top of their games, but Roddick has too much experience for his younger opponent.  The experience Sock will take from this match will be invaluable to him as he starts his pro career. 

Pull up a seat, get some popcorn and enjoy watching the present and future of American men's tennis.

Prediction: Roddick in 3

U.S. Open Match to Watch: Day 4

You could do a lot worse than watching a mid afternoon match on the Grandstand between Jo-Wilfriend Tsonga of France and Sergei Bubka of the Ukraine.

Tsonga remains one of the most entertaining players to watch on the men's tour and if the name Sergei Bubka seems familiar to you, this is the son of the famous pole vaulter, Sergei Bubka.

Expect to see Tsonga blasting forehands from corner to corner, and Bubka to unload on big first serves.  Bubka recently surpassed the 150mph mark on a first serve he hit at a tournament in Canada.

Tsonga will win the match, but I can't wait to watch it unfold.

It's Radwanska vs. Radwanska at the U.S. Open

Tennis draws can sometimes lead to some strange matchups.  At Wimbledon this year, we saw a blind draw that resulted in the rematch of the longest tennis match in history, Isner vs. Mahut.

This year, with Urszula Radwanska winning three qualifying matches, she was added to the U.S. Open Women's Singles Draw to play none other than her sister, #12 seeded Agnieszka.

The two have actually played twice on the WTA Tour, in addition to I'm sure what were numerous knockdown dragouts on the courts of Krakow, Poland.

Each sister has one win the career head-to-head.  Urszula won in Dubai in 2009 and Agnieszka won in 2009 at Eastbourne. 

Hope this match gets put on a decent court on Monday or Tuesday, so a big crowd can take in this matchup of tennis siblings.
