Ana Ivanovic Ousted In 1st Round Of US Open Again

NEW YORK (CBSNewYork/AP) -- Ana Ivanovic is out of the US Open in the first round for the second straight year after losing 7-6 (4), 6-1 to Denisa Allertova of the Czech Republic on Tuesday.

Ivanovic is a former No. 1 player and 2008 French Open winner who has slipped to No. 31 in the rankings.

The Serb was serving for the first set at 6-5 but struggled with her serve and faltered in the tiebreaker. She finished with seven double-faults and 41 unforced errors.

At the Open, she has reached the fourth round or better five times, including a career-best quarterfinal run in 2012.

The 89th-ranked Allertova improved to 7-1 in first-round matches in majors, making her second main-draw appearance at the Open.

Earlier Tuesday, Simona Halep quickly took care of Kirsten Flipkens, 6-0, 6-2.

The Romanian was ahead 6-0, 5-0 with countrywoman Nadia Comaneci cheering her on. Comaneci was the first gymnast to score a perfect 10 at the 1976 Montreal Olympics.

Halep gave herself "less than 9" for her performance, but said she was pleased with how she played against the Belgian. She got 69 percent of her first serves in and won 12 of 15 points at the net.

Halep, who reached the semifinals of the US Open last year, will next face Lucie Safarova, a 6-4, 6-4 winner over Daria Gavrilova.
