NEW YORK (Reuters) -American Taylor Fritz kept the Stars and Stripes fluttering at the U.S. Open on Sunday by swatting aside Czech Republic's 21st seed Tomas Machac 6-4 6-3 6-3 to book his spot in the quarter-finals of the Grand Slam for the third consecutive year.
Last year's runner-up Fritz is the sole American man left from the 23 who began the main draw and also the nation's last hope of ending a 22-year major drought since Andy Roddick held aloft the sterling silver trophy at Flushing Meadows in 2003.
