Del Potro advances to 3rd round at Australian Open

Juan Martin del Potro has defeated Benjamin Becker 6-2, 6-4, 6-2
to advance to the third round of the Australian Open without
dropping a set.

The 2009 U.S. Open champion is one of only four men left in the
draw with a Grand Slam title, along with Roger Federer, Andy Murray
and Novak Djokovic.

The sixth-seeded del Potro had 22 aces and 50 winners Thursday
night against the overmatched Becker, who had just one breakpoint
chance in the match.

Del Potro last year equaled his best result at the Australian
Open by making the quarterfinals, where he lost to Federer.
