Defending U.S. Open champion Juan Martin del Potro is on the provisional entry list for the year's last Grand Slam tournament, despite being sidelined nearly all season because of right wrist surgery.The U.S. Tennis Association says Thursday that del Potro "is expected" to compete at the hard-court major championship, which begins Aug. 30.
All top 98 men in the rankings are on the entry list, led by No. 1 Rafael Nadal, who will try to complete a career Grand Slam by adding a U.S. Open title to his five French Opens, two Wimbledons and one Australian Open.
Del Potro won his first Grand Slam title by beating five-time U.S. Open champion Roger Federer in the 2009 final. The Argentine has played one tournament in 2010, the Australian Open.
