Wozniacki, Ivanovic win 1st-round matches in Qatar

The 10th-ranked Wozniacki beat qualifier Mervana Jugic-Salkic 6-1, 6-2. The Dane had a poor start, losing her serve in the first game. But she broke right back and cruised from there, wrapping up the win in just over an hour.

The 13th-ranked Ivanovic beat Tamira Paszek 6-1, 6-2. Ivanovic broke the 26th-ranked Austrian twice in the first set, then saved three break points to go up 4-2 in the second. She broke Paszek again to make it 5-2 and sealed the victory when the Austrian hit a return long.

Wozniacki, a fourth-round loser in the Australian Open, said she felt comfortable against an opponent she had never faced.

"I just tried to focus on my own game and felt like I served well, returned well. I was happy," she said.

Wozniacki's father, Piotr, was courtside during the match, counseling her at one point. He returned to the role of coach after the U.S. Open and the 22-year-old Dane said she felt she "needed the calmness" of her inner circle. She fired coach Ricardo Sanchez a year ago after two months on the job.
