Flushing Meadows, NY (Sports Network) - Five-time champion Roger Federer moved on in straights sets Tuesday at the U.S. Open.
The seventh-seeded former world No. 1 great handled Slovenian Grega Zemlja 6-3, 6-2, 7-5 at Arthur Ashe Stadium in a match that was postponed because of rain on Monday night.
The 17-time Grand Slam titlist Federer was the tennis king of New York from 2004-08 and runner-up in 2009.
Up next for the Swiss icon will be Argentine Carlos Berlocq.
Top American John Isner reached the second round, as the 13th-seeded 6-foot-8 slugger was efficient in dismantling helpless Italian Filippo Volandri, 6-0, 6-2, 6-3, in only 1 hour, 16 minutes on the Grandstand court. The massive- serving Isner fired 16 aces on Day 2.
The surging Isner recently titled in Atlanta and was a hardcourt runner-up in Washington, D.C., and at an ATP Masters 1000 event in Cincinnati.
Meanwhile, 10th-seeded 6-foot-5 rising Canadian Milos Raonic handled diminutive Italian Thomas Fabbiano, 6-3, 7-6 (8-6), 6-3, on a warm, breezy day at the USTA Billie Jean King National Tennis Center. The powerful Raonic unleashed 28 aces, compared to zero by the overmatched Fabbiano.
A surprising Day-2 upset came when 30-year-old Argentine qualifier Maximo Gonzalez upended 14th-seeded 6-foot-8 Pole Jerzy Janowicz, 6-4, 6-4, 6-2. Janowicz reached his first-ever Grand Slam semifinal at Wimbledon just last month.
Also on Tuesday, 22nd-seeded German Philipp Kohlschreiber whipped 17-year-old American Collin Altamirano, making his ATP-level debut, 6-1, 6-3, 6-1; Portuguese Joao Sousa erased 25th-seeded Bulgarian Grigor Dimitrov, 3-6, 6-3, 6-4, 5-7, 6-2; 26th-seeded American Sam Querrey bested Argentine Guido Pella, 7-6 (7-3), 4-6, 6-1, 6-2; and 31st-seeded quality Frenchman Julien Benneteau got past Poland's Michal Przysiezny, 6-4, 5-7, 6-4, 6-4.
Also advancing was French former top-10 star Gael Monfils, who drubbed Romanian Adrian Ungur, 6-1, 6-2, 6-0, to set-up a second-rounder with Isner.
