NEW YORK(AP) Former world No. 1 Ana Ivanovic has made her second straight early exit from the U.S. Open, falling 2-6, 6-3, 7-6 (7) to Kateryna Bondarenko in the opening round.

Last year, Ivanovic lost in the second round, the earliest a top-seeded woman has ever been eliminated at the U.S. Open.

The 2008 French Open winner came to Flushing Meadows this year slumping, seeded 11th, and wound up with an even worse result. She lost Tuesday to Bondarenko, a Ukrainian ranked 52nd in the world.

Ivanovic had a match point, but leading 6-5 in the tiebreaker, she netted an easy forehand. Bondarenko double-faulted on her first match point, but won the next two points, wrapping it up when Ivanovic hit another forehand into the net - her 50th unforced error.
