John Isner def Xavier Malisse (6-3, 7-6, 5-7, 7-6): For the power serving Isner who is currently ranked among the top 10 in the world, this match was a bit touch and go at times. He started strong with an early break against Malisse but as the match progressed Malisse gained steam and took the third set from Isner. Big John kept his cool though and America's best hope on the men's side to win, came through in the fourth set with a tiebreak victory. Knowing that he needs to play economically in the early rounds, Isner getting through without the need of a fifth set should benefit him going forward.
Ryan Harrison def Benjamin Becker (7-5, 6-4, 6-2): The young Harrison has seemed to improve each year he has been on the professional tour. Having won this match against Becker, the 20-year-old will finish the best year of his career including two second round appearances at Wimbledon and the US Open. He is currently ranked outside of the top 50 as he has had a rough month but in early July he sat as the No. 42 player in the world. He has a good game and many expect he could be a future star for the U.S.
Bradley Klahn def Jurgen Melzer (4-6, 6-3, 7-5, 5-7, 6-4): In just his second grand slam appearance, Klahn played incredibly well and upset Melzer. The 22-year-old American managed to best his opponent and win his first round match. For Klahn, who is ranked just barely within the top 500 in the world, this was just his first win on the professional tour.
Brian Baker def Jan Hajek (6-3, 6-4, 6-2): Baker's story is one of inspiration and determination. Formerly a top junior in the world, Baker's career was derailed by injuries and surgeries. Just a few years ago he was entirely out of the sport. When he made his comeback this year it was certainly one to follow especially since he was playing back to the level he was during his best days. In just his first US Open since 2005, Baker is hoping to have a great showing in front of the New York crowd.
Steve Johnson def Rajeev Ram (6-3, 7-6, 6-3): Johnson already began his 2012 US Open on a great note as he and partner Jack Sock defeated the No. 1 doubles team in the world. Entering the singles competition, the No. 245 player in the world was still looking for his first singles win at a grand slam. Having lost in the first round last year, Johnson improved upon that and beat fellow American Ram to reach the second round. As part of a great day for the Americans, the veteran Ram was the only American to lose in singles.
Mallory Burdette def Lucie Hradecka (6-3, 4-6, 6-2): Making her grand slam singles debut, Burdette already worked hard to win qualifying tournaments to make the main draw. She upset her opponent to win her first round match and as it seems to happen every year for an American at Flushing, so far continued her inspired run with a second round victory against Hradecka. Having only made it as far as the second round in doubles at the 2011 US Open, Burdette assured herself a career best performance with the victory.
Varvara Lepchenko def Anastasia Rodionova (6-2, 6-2): Lepchenko has seen such a career upswing since moving to America to train and recently even becoming an American citizen. She is currently having the best season of her career and that was aided by another victory at the second round of the 2012 US Open.
WOMEN'S DOUBLES - Eight American teams began play, five advance to the second round
1. Serena Williams/Venus Williams def Lindsay Lee-Waters/Megan Moulton-Levy (6-4, 6-0): After winning Wimbledon and the Olympic Games, there was really no doubt that the Williams sisters would come back to try to claim another US Open title. Both are healthy and Serena is coming back to have a great 2012 season. Both also won their singles first round matches and once again one of them could win the doubles and singles titles.
2. Raquel Kops-Jones/Abigail Spears def Dominika Cibulkova/Daniela Hantuchova (4-6, 6-1, 6-2): Needing three sets, the young pair of Kops-Jones and Spears beat their opponents after falling behind after the first set. The No. 9 seeded doubles team, the American pair is taking a run at their first doubles title in a grand slam.
3. Irina Falconi/Maria Sanchez def Alexandra Cadantu/Mathilde Johansson (6-2, 6-3): It was a pretty easy match for Cadantu and Johansson as they beat the American pair. Falconi and Sanchez were out of the match early and could not recover from two early breaks in both sets.
4. Madison Keys/Jessica Pegula def Akgul Amanmuradova/Monica Niculescu (6-2, 6-2): At just 16 years old, Keys, who had never been out of the first round of a major paired with the 18-year-old Pegula who reached the third round of last year's US Open. This year, the two played very well together and easily won their first round match.
5. Vania King/Yaroslava Shvedova def Polona Hercog/Andreja Klepac (6-0, 6-1): Paired with Shvedova of Kazakhstan, American Vania King is part of the fifth seeded doubles team in this US Open. In a very decisive first set followed by another near perfect second set, the team disposed of their Slovakian opponents in a dominant straight sets victory.
Silvia Soler-Espinosa/Carla Suarez Navarro def Grace Min/Melanie Oudin (6-1, 6-4): Despite a strong effort in the second set, the young American team of Min and Oudin were unable to overcome their weak performance in the first set. With just one additional break needed in the second, the Americans were ousted by the Spanish team quickly.
Sara Errani/Roberta Vinci def Varvara Lepchenko/Saisai Zheng (6-4, 7-5): Although Lepchenko is having a great season with singles, her doubles performance has not exactly been as good. In the 2012 US Open, paired with Zheng of China, the team lost in a close first round match against the No. 2 seeded team of Errani and Vinci.
MEN'S DOUBLES - Three American teams began play, two advance to the second round
1. Mike Bryan/Bob Bryan def Steve Darcis/David Goffin (6-1, 6-4): Looking to reclaim their title as the best doubles team in the world, the Bryan Brothers have been having a great season. They finished twice as runner up at the Australian and French Open and then went on to a semifinal finish at Wimbledon. After that, they finally completed their career golden slam with the gold in doubles at the Olympic Games. Now, they are looking for their first slam of the year and their fourth US Open.
2. Dennis Novikov/Michael Redlicki def Bobby Reynolds/Michael Russell (6-4, 2-6, 7-6): In another all-American match, the team of grand slam rookies in Novikov and Redlicki bested their opponents in three sets.
3. Treat Conrad Huey/Dominic Inglot def James Blake/Sam Querrey (6-1, 7-6): In one of the few matches that saw an American pair lose, the team of Blake and Querrey lost in straight sets. Having paired together for the first time, Blake and Querrey never really found chemistry on the court. They played well in the second set but could not pull out the victory.
MIXED DOUBLES - Three American teams began play, one advances to second round
1. Sania Mirza/Colin Fleming def Andrea Petkovic/Eric Butorac (6-2, 7-6): Playing in mixed doubles at the US Open for the first time, the veteran Eric Butorac was looking to make it out of the first round. With his partner in Petkovic, the two battled especially in the second set but ultimately were unable to beat Mirza and Fleming.
2. Sloane Stephens/Rajeev Ram def Bethanie Mattek-Sands/Horia Tecau (6-2, 5-7, 1-0): In another match that saw two at least partially American teams, the young Stephens paired with the veteran Ram came back from a set all to win. The American Mattek-Sands and her Romanian teammate played well but ultimately were forced to retire in the third set giving the victory to the team of Stephens and Ram.
