Five Matches to Watch on Day 5 of the US Open

1. Andy Murray (GBR)[4] v. Dustin Brown (JAM) -- Though he speaks German and spends much of his time in Germany and the rest of Europe, Dustin Brown has gained a lot of attention for flying the Jamaican flag, putting a country previously only known for sprinters and bobsledders (I can hardly describe how much I love Cool Runnings) on the tennis map.  Those who have watched him play (of which I am not one, yet) say that he's an extremely entertaining guy to watch, what with the flashy shotmaking and the dreadlocks.  Andy Murray rolled in his first round match against Lukas Lacko, but it would be nice to see him get more of a challenge against someone who should be a fun opponent.

2. Marco Chiudinelli (SUI) v. John Isner (USA)[18] -- John Isner's gimpy left ankle held up extremely well against the un-threatening Frederico Gil in the first round, but Marco Chiudinelli is a far more imposing opponent.  Chiudinelli made a surprising run to the third round of this tournament last year, and is an aggressive player who will be much tougher for Isner to break than Gil was.  Isner does have the added benefit of more time to recover from the ankle injury he suffered in Cincinnati, an injury that should become less and less of an issue as this tournament progresses.  But if he's not 100%, he could easily go out today.

3. Virginie Razzano (FRA) v. Ana Ivanovic (SRB) -- Two of the bigger names of the unseeded ranks meet on Louis Armstrong Stadium for a spot in the fourth round against the winner of Petra Kvitova vs. Kim Clijsters.  On recent form, Ivanovic should definitely be the favorite in this match, with her dominant win over Zheng Jie on Day 3 and run to the semifinals of Cincinnati.  But Razzano is a tricky opponent who puts an incredible amount of spin on her groundstrokes, and could give the flat-hitting, margin-less Ivanovic trouble, especially if the approaching winds of Hurricane Earl play a role.

4. Francesca Schiavone (ITA)[6] v. Alona Bondarenko (UKR)[29] -- After shutting down the Melanie Oudin hype machine, Alona Bondarenko faces another diminutive but emotive player in the third round, French Open champion Francesca Schiavone.  Schiavone had struggled mightily between her French Open win and Montreal, but she seemed to get back on track at that tournament and has looked sharp early this week.  Both of these two can always be counted on for long rallies and multiple emotional outbursts each match, so bring popcorn.

5. Gilles Simon (FRA) v. Philipp Kohlschreiber (GER)[29] -- This might be the best match-up on Court 13 this entire tournament.  Both Simon and Kohlschreiber are slight guys with big games, flashy shotmaking, and impressive speed.  There will definitely be some highlight reel stuff coming off this one.  I just hope enough people watch to let everyone else know how awesome it was.
