MELBOURNE, Jan. 19 (UPI) -- Novak Djokovic and Andy Murray, last year's tournament finalists, advanced to the third round of the Australian Open with straight-set wins Thursday.
Djokovic, the world No. 1 and defending Australian Open champion, was a 6-3, 6-2, 6-1 winner over Santiago Giraldo. He won about three-quarters of the points on serve -- facing two break points but none after the first set -- and 52 percent of the points receiving.
Murray, seeded fourth this year, took a 6-1, 6-4, 6-4 decision from Edouard Roger-Vasselin. He was good on 68 percent of his first serves, winning 85 percent of the points in those situations. The only break point he faced came in the third set.
Fifth-seeded David Ferrer played almost 3 1/2 hours before escaping a challenge from Ryan Sweeting 7-6 (7-4), 2-6, 6-3, 2-6, 6-3. The first set alone took 69 minutes.
No. 6-seeded Jo-Wilfried Tsonga defeated Ricardo Mello 7-5, 6-4, 6-4 and ninth-seeded Janko Tipsarevic rallied for a 3-6, 6-2, 7-6 (7-5), 6-4 win over James Duckworth.
Five men's seeds exited the draw Thursday. That included No. 15 Andy Roddick, who won his first set but suffered a hamstring injury and retired after Lleyton Hewitt went up 3-6, 6-3, 6-4.
