What We’re Watching on Day 4

James Blake vs. Steve Darcis

Mardy Fish vs. Paul-Henri Mathieu

Sam Querrey vs. Nicolas Devilder
Day 4 is a good time to take the temperature of American men at the tournament, as one of the United States’ biggest stars and two of its most promising young players all have second-round matches. James Blake should be able to beat Steve Darcis, but after being taken to five sets by Donald Young the other night, it will be interesting to see how he’s looking. Mardy Fish is the definite underdog against 24th-seeded Paul-Henri Mathieu, but Fish can be dangerous. The match between Sam Querrey and Nicolas Devilder is more evenly matched, and Querrey will have lots of support in the stands. However, a lot of unforced errors in his losing doubles match last night alongside John Isner don’t bode well.

Rafael Nadal vs. Ryler De Heart
All eyes continue to be on first-seed Nadal, as he takes on yet another young American. Nadal struggled a little in his first round match, but De Heart couldn’t quite articulate a way to beat him. We’ll see if he can demonstrate it.

Ai Sugiyama vs. Olga Govortsova
I think Sugiyama is great, and she has a way of getting her way into the third or fourth round of majors.

Davenport/Bryan vs. Poutchek/Kas
A mixed doubles match with two excellent doubles players in Americans Lindsay Davenport and Mike Bryan.

Juan Martin Del Potro vs. Thomaz Bellucci
Del Potro won his first round match convincingly in four sets against Guillermo Canas. He got to the third round here last year, and there’s no reason he can’t get even farther this time.
