Federer in action on opening day of U.S. Open

NEW YORK: Roger Federer looks to cap an "incredible" season when he launches his bid for a sixth U.S. Open title against American Donald Young on Monday.

Federer beat Briton Andy Murray to win the 2012 Wimbledon title, regained his world number one ranking and comes into the final grand slam of the year in ominous form.

Murray, who lost to Federer in the Wimbledon final but beat the Swiss weeks later at the same venue to win gold at the London Olympics, is also in action on Monday against Russian Alex Bogomolov Jr.

Also taking the court on Monday will be last year's women's winner Samantha Stosur, as well as former champions Maria Sharapova, who completed her career grand slam this year at the French Open, and three-times U.S. Open titlist Kim Clijsters.

Clijsters, who faces American Victoria Duval, will retire after the tournament.

Sharapova, who won at Flushing Meadows in 2006, will face Hungary's Melinda Czink in her opening-round match. The Russian has not played since winning a silver medal at the Olympics.(Reuters)
