Sam Querrey beat Alejandro Falla for the second time in less than a week, defeating the Colombian 6-3, 6-3 in a first round match at the US National Indoor Championships. Querrey, who won the Memphis title three years ago, hammered six aces and won 74 percent of his first-serve points as he needed just 58 minutes to eliminate Falla. Fourth seed Querrey also beat Falla in the quarter-finals of the San Jose tournament on Friday. Querrey, who is the No. 2 ranked American on the ATP Tour, advances to the second round where he will face the winner of a match between Japan\'s Go Soeda and Marinko Matosevic of Australia. Defending champion Jurgen Melzer crashed out of the joint ATP and WTA tournament, losing his opening-round match in straight sets at The Racquet Club of Memphis. The left-handed Austrian lost to Dutchman Igor Sijsling 6-4, 7-6 (7/3). Sijsling advanced to a second-round match against Croatian top seed Marin Cilic. Melzer, who was playing with a broken toe, defeated Milos Raonic in last year\'s final, snapping the Canadian\'s win streak at nine straight matches. In other matches, American veteran James Blake defeated German Florian Mayer 4-6, 6-3, 6-2. On the women\'s side, Slovakian seventh seed Magdalena Rybarikova reached the third round by ousting American Lauren Davis 7-6 (7/2), 6-2. France\'s Claire Feuerstein upset Czech fifth seed Lucie Hradecka 6-3, 6-4 while German third seed Sabine Lisicki reached the second round with a 7-5, 6-3 victory over American Madison Keys. From: AFP
