KEY BISCAYNE, Fla. - No. 1-ranked Rafael Nadal and No. 2 Novak Djokovic advanced to the Sony Open final without playing a point on Friday. Both received walkovers when their semifinal opponents withdrew for health reasons. That left Nadal and Djokovic to play for the title on Sunday in their 40th career meeting and their first of 2014. Djokovic was given a walkover for the second time in the tournament when Kei Nishikori withdrew because of a left groin injury. Four hours later, Tomas Berdych pulled out before his match against Nadal due to gastroenteritis. The wave of ailments left the tournament with only two womens doubles matches for disappointed spectators. Former No. 1 Martina Hingis advanced to her first doubles final since 2007 when she and Sabine Lisicki beat Cara Black and Sania Mirza 6-3, 6-4. On Saturday, No. 1 Serena Williams will try for her seventh Key Biscayne title when she plays No. 2 Li Na — health permitting. Djokovic also received a walkover in the third round and has played only six sets in the tournament. Hes seeking his fourth title in the event, while Nadal is 0-3 in Key Biscayne finals, one of only three ATP Masters 1000 tournaments he has yet to win. Djokovic will try to complete a March sweep Sunday. He won the Indian Wells title two weeks ago, when he beat Federer in the final. Nadal leads his rivalry with Djokovic, 22-17, and they went 3-3 last year. Regardless of Sundays outcome, Nadal will remain No. 1 and Djokovic No. 2 next week. A disappointed Nishikori pulled out less than two hours before his semifinal. "I tried to warm up and I couldnt move" Nishikori said. "With anybody on the other side, I dont think I could win today." Berdychs withdrawal was announced an hour before his match. That spared him from having to face a player who has won their past 16 meetings. Nishikori said his groin has bothered him for more than a month, and he retired during a match in Delray Beach last month. This week he won a won a three-set match against David Ferrer, saving four match points, and then beat Roger Federer in a three-setter Wednesday night. The No. 21-ranked Nishikori said he wont need surgery, but hes unsure how long hell be sidelined and will fly home to Japan to see a doctor. His next scheduled match is in Davis Cup for Japan against the Czech Republic in Toyko on April 4. Nishikori has retired or withdrawn 14 times in his career, including three times in Grand Slam events. He was hoping to reach his first ATP Masters 1000 final. "It was going to be a great challenge for me today," Nishikori said. "Hopefully I can play another time." Three of the past six Key Biscayne mens semifinals have been cancelled. Nadal withdrew because of a knee injury in 2012, giving Andy Murray a walkover. Spectators on Friday will be offered a chance to exchange their tickets for a session at the 2015 tournament.

The 44-year-old Scot rebounded from a bogey on the par-4 12th — her third hole in the morning round — with the eagle on the par-5 13th and birdied seven of her final 11 holes. "That kind of kick-started my round," Matthew said about the eagle. She won the last of her four LPGA Tour titles in 2011. "Obviously, really pleased," Matthew said. "Just had two weeks at home, so never quite know what youre going to come out and play like. So, yeah, delighted. Got the putter going and holed some putts." Charley Hull had a bogey-free 65 in the afternoon. The 18-year-old English player birdied the final two holes on the Crossings Course at the Robert Trent Jones Golf Trails Magnolia Grove complex. "I putted quite well, hit it quite solid, and hit, I think, every green," said Hull, playing on a sponsor exemption. "I still left a few shots out there. I missed a 3- or 4-footer, but hey, another day tomorrow and hopefully I can go low." Second-ranked Stacy Lewis, No. 4 Suzann Pettersen and South Koreas Eun-Hee Ji shot 66. Lewis, the 2012 winner, finished her first nine with birdies on Nos. 15-18.

The Texan won the North Texas LPGA Shootout three weeks ago for her ninth tour title. Last week in Virgiinia, she closed with a 74 to tie for 12th in the Kingsmill Championship.dddddddddddd "Coming off of last week where I didnt hit the ball well, I was happy with the way I drove it today," Lewis said. "I hit it solid and made some putts. Figured something little out in my putting and I think that might help the rest of the week." Pettersen, playing her fourth event since returning from a back injury, had a bogey-free round. "Im feeling pretty good, felt pretty calm," Pettersen said. "I feel like my game is right there, trying to be patiently aggressive. Playing smart on the hole locations that arent quite set up for being aggressive and then trying to take advantage. But the greens are fairly receptive, so it feels like you can kind of fire at the pin and not have to worry about too much spin, which makes this course a little bit easier." Ji, the 2009 U.S. Womens Open champion, birdied four of the five holes in a bogey-free round. "I felt good this morning when I was warming up," Ji said. "Feel good with my swing and with my putter. Was out there like, I can see the green. I can see the line. So I just made a lot of putts." Bahamas winner Jessica Korda was three strokes back at 67 along with 2010 champion Se Ri Pak, Nicole Castrale, Julieta Granada, Moira Dunn and Jenny Shin. Pak also won the Tournament of Champions on the course in 2001 and 2002. Anna Nordqvist, a two-time winner this year, had a 68, and Kraft Nabisco winner Lexi Thompson opened with a 70.
