James Blake (USA) vs Daniel Gimeno-Traver (ESP) - A good match-up for Blake here. The American's form has been patchy in 2010 but Gimeno-Traver's game isn't suited to a fast hardcourt. Blake to move comfortably into round two.
Dudi Sela (ISR) vs Jesse Levine (USA) - This will be a good contest. Sela is a grinder who will be consistent from the baseline all match. Levine plays well at home and was granted a wildcard, so he will be primed for this one. I think he can get the win over the Israeli who isn't at his best so far this season.
Stefan Koubek (AUT) vs David Nalbandian (ARG) - Koubek came through the qualifying, so he is match hardened. Nalbandian was impressive last week, helping Argentina win in Sweden last week in the Davis Cup. I think the Argentine with have too much class and poise for the feisty Austrian.
Robby Ginepri (USA) vs Andreas Seppi (ITA) - Ginepri is horribly out of form, but I think he can defeat Seppi here. The Italian will frustrate Ginepri at times with his consistency, but the American seems to lift a level when playing in the States. This will go the distance, with Ginepri just edging it.
Richard Gasquet (FRA) vs Simon Greul (GER) - If the real Richard Gasquest comes to play, he will get past Greul with ease. But we know the Frenchman often leaves his best for when it doesn't count. The German is a solid player but he will be outclassed heavily on this occasion. Gasquet in two sets.
Sergiy Stakhovsky (UKR) vs Wayne Odesnik (USA) - The Ukrainian is a tricky player, but I prefer him more on the indoor surfaces. Odesnik is a battler, but is always up for the challenge. He should be more suited to the hot and windy conditions than Stakhovsky. A gritty win to the American.
Paolo Lorenzi (ITA) vs Michael Russell (USA) - Lorenzi is a journeyman who has done well over the past year, returning to the top 100. He faces Russell who loves a fight, and this match-up looks a good fit for the veteran American. Russell in straight-sets.
Nicolas Almagro (ESP) vs Mischa Zverev (GER) - The Spaniard has had a reasonable start to the season, and is a capable player on a hardcourt. Zverev goes through hot and cold spells, so Almagro will be wary of that. The German is better suited on an indoor court so I'm tipping the Spaniard to move into round two.
Paul-Henri Mathieu (FRA) vs Benjamin Becker (GER) - An interesting match here. The skillful Frenchman can beat anyone on his day, but also lose winnable matches regularly. Becker has plenty of experience in American conditions and is good enough to beat Mathieu here. The German in three sets.
Victor Hanescu (ROU) vs Juan Ignacio Chela (ARG) - Both guys prefer clay, but Hanescu's form is steadily improving while the Argentine's in on the decline. The Romanian handled Chela easily in the Australian Open and he can do it again in this match. Hanescu to face Federer in the next round.
Yen-Hsun Lu (TPE) vs Oscar Hernandez (ESP) - Lu breezed through qualifying and he will be happy with his first round opponent. Hernandez battles in the big tournaments and on hardcourts in general. Lu will get the victory in a hurry, easily in two sets.
Michael Llodra Llodra (FRA) vs Marinko Matosevic (AUS) - Should be a non-contest here. Llodra is an experienced campaigner, while Matosevic spends most of his season on the challenger circuit. The Aussie did well to make the main draw, but Llodra will win comfortably.
Ricardo Mello (BRA) vs Horacio Zeballos (ARG) - Mello loves the hardcourts and has had solid results in 2010. Zeballos is a tough player and is always hard to beat. But with some good qualifying wins, the Brazilian will win a close three-set battle here.
Florian Mayer (GER) vs Evgeny Korolev (KAZ) - Mayer is not the opponent Korolev would like to face. He plays crafty unorthodox tennis, and It will upset Korolev who loves the fast pace. The former Russian is a quality player with all the shots, but I don't like this match-up for him. The German in three sets.
Arnaud Clement (FRA) vs Peter Luczak (AUS) - This could go a while. Both veterans love slugging it out from the baseline with long grueling rallies. Luczak prefers clay and as tough as he is, doesn't have many outstanding results at the ATP 1000 level. Clement is an all-round player and plays well in outdoor conditions. He will win this and move into round two.
Thiemo de Bakker (NED) vs Marcos Daniel (BRA) - Both spend most of the season on the challenger tour, but the Dutchman's form on fast hardcourts is far superior than Daniel's. The Brazilian battles when playing at the top level and de Bakker will move into the next round in straight-sets.
