Roger Federer looks to clinch 20th Grand Slam singles title

MELBOURNE, Australia — Roger Federer will attempt to win his 20th Grand Slam singles title when he plays Marin Cilic in the Australian Open final on Sunday night.

Federer, the defending champion at Melbourne Park, is also vying for his sixth title here.

The Swiss star owns an 8-1 head-to-head record and defeated Cilic in straight sets in last year's Wimbledon final, although Cilic was affected by blisters in that match.

The mixed doubles final will open play Sunday at Rod Laver Arena. Rohan Bopanna and India and Hungary's Timea Babos will play Gabriela Dabrowski of Canada and Croatia's Mate Pavic.

On Saturday, Caroline Wozniacki won her first Grand Slam title and took the No. 1 ranking from Simona Halep with a three-set win over the Romanian player in the women's final.
