DUBAI, United Arab Emirates -- Defending champion Novak Djokovic needed less than an hour to advance at the Dubai Championships on Wednesday, while Roger Federer faced a struggle to seal his place in the quarterfinals. Top-seeded Djokovic swept to a 6-1, 6-3 win over 51st-ranked Roberto Bautista Agut of Spain in just 57 minutes, but fourth-seeded Federer had to see off a serious challenge from 48th-ranked Radek Stepanek of the Czech Republic before coming through 6-2, 6-7 (4), 6-3. "I have done really well today from the first to the last point," Djokovic said. "There was no major ups and downs, especially with the serve that helped me to win comfortably my service games, a lot of free points." In the first set, Djokovic raced to a 5-0 lead before Bautista Agut held serve to win his only game in the set. The only hiccup Djokovic had in the second set was when serving for the match at 5-2. He dropped his serve in that game but broke serve in the next to close out the match. Djokovic will play sixth-seeded Mikhail Youzhny, who beat British wildcard recipient James Ward 6-1, 7-6 (3). Federer came into his two hour, eight minute match with a 12-2 winning record over Stepanek. Hes now won their last nine meetings dating back to the 2008 Rome quarterfinals. "I got broken four times which is difficult, but its good to win those type of matches," said Federer, who faced eight break points against his serve. "Im happy to get through. "It didnt look good there for a while, but I got it done." Federer handled the first set with confidence, but started to falter as Stepanek became more aggressive in the second set. Federer managed to rebound from 4-2 down in the second set to force a tiebreaker -- where Stepanek raced into a 6-2 and a first set point when Federer double faulted. Stepanek won the set on his third set point when Federer netted a forehand. Stepanek also took an early 2-0 lead in the third set, but Federer rebounded to go ahead 5-2 to serve for the match. Federers serve was broken when he double faulted in the eighth game. Stepanek, however, surrendered his serve in the next game to allow Federer to move into the quarterfinals. Hell now face another Czech player in Lukas Rosol, who upset eighth-seeded Dmitry Tursunov of Russia 6-4, 7-6 (4). "Today was quite frustrating," Federer said. "I had momentum on my side at the beginning, but it was tough to keep it going. "After the first set I was under pressure the entire match." Like Djokovic, third-seeded Tomas Berdych had an easy path to the quarterfinals with a 6-2, 6-1 win over Sergiy Stakhovsky of Ukraine. Berdych, who will face fifth-seeded Jo-Wilfried Tsonga in the quarterfinals, has won his last eight matches. Despite Berdych having trouble with his first serve -- his percentage was a ghastly 37 per cent -- he controlled the match. He lost his serve once, and won 12 of the last 14 points. "I was working a little more on my return stats than on my service stats," Berdych said. "The main focus really for the next days is to get my percentage of the first serve back and really find a nice and sweet rhythm for my serve." Tsonga won his second-round match by walkover when his opponent, Nikolay Davydenko, withdrew with a rib injury. Seventh-seeded Philipp Kohlschreiber was a 6-3, 6-3 winner over Andrea Seppi of Italy. Kohlschreiber will play Tunisian wild card Malek Jaziri, who beat Somdev Devvarman of India 6-3, 7-5. Air Jordan Retro 4 Discount . Others describe it as taking the parrot for a walk.

One day after Scott opened with a record-tying 62 in the Arnold Palmer Invitational, he hit his stride around the turn Friday with five birdies in an eight-hole stretch to leave everyone else far behind. Even with a three-putt bogey on his final hole, Scott still had a 4-under 68 for a seven-shot lead. He was at 14-under 130, matching the 36-hole record at Bay Hill first set by Tom Watson and Andy Bean in 1981. And his seven-shot margin at the halfway point shattered the previous record held by Tiger Woods in 2002 and Paul Azinger in 1988. Scott sounds like hes not the least bit satisfied. "The challenge might be just to start again and try and play a great 36 holes," he said. "Start fresh and try to be the leader after the next 36." That would merit a visit with Arnold Palmer, the tournament host known simply as "The King" in golf circles. Scott has spoken glowingly all week about his first invitation to Bay Hill when he was 20. Walking off the first green, Palmer was in a cart to greet him with a handshake, and Scott was amazed that Palmer knew his name. Now hes the Masters champion, and the 33-year-old Australian is playing like one. J.B. Holmes (69), Chesson Hadley (68) and Francesco Molinari of Italy (70) were tied for second at 7-under. Keegan Bradley had the low score of the blustery second round with a 67, putting him in a group at 138 that included Brandt Snedeker (71) and Jamie Donaldson of Wales (71). "I think Im 10 behind and playing pretty well for two rounds," said Snedeker, who was off by two. "Hes playing pretty phenomenal. Hes going to be a tough guy to catch. A guy that hits it as good as he does and seems to have a complete game like he has, and the way hes playing now, hes not going to come backward. Seems like an awfully special week if you can get close to him." Scott played in the afternoon, when the course began to get firm under two days of full sunshine, and the pace on the greens began to quicken. No one ever got closer than his three-shot lead to start the round, though there were two pivotal moments. He holed a 15-foot par putt on the first hole to calm his nerves, and he hit a gorgeous shot out of the rough from 167 yards and made a 12-foot birdie on the ninth. He went to the back nine 1-under par for his round, and he took off from there. Scott hit a 7-iron to 4 feet on No. 11,, got up-and-down for birdie on the par-3 12th, nearly holed a tough chip from behind the 14th green to save par, and then made consecutive birdies with a 30-foot putt on the 15th and a 7-iron to pin-high for a two-putt birdie on the par-5 16th.dddddddddddd He only made it look easy. There were three rounds in the 80s, including by U.S. Amateur champion Matthew Fitzpatrick. U.S. Open champion Justin Rose, playing in the same group with Scott, had a 79 and missed the cut for the first time in a regular PGA Tour event since The Players Championship last May. "This course will really start to bare its teeth," Scott said. "Ive got to take in the attitude of starting over again and trying to play a really hard 36 holes. And hopefully, if I can I can keep striking the ball like I am, Ill give myself enough chances for birdie — and hopefully, more birdies than bogeys." At one point, caddie Steve Williams was some 275 yards down the left side of the fairway on the par-5 16th. His boss was barely visible back on the tee, but Williams watched his swing and instantly said, "Perfect." And that it was, 325 yards right down the middle. Scott missed only two fairways and has taken just 52 putts over the first 36 holes. He was in no mood to celebrate just yet. For one thing, he is still recovering from being sick. His energy was better Friday, though he could barely talk above a whisper during a brief interview with Golf Channel before his round. And the Australian knows how a big lead can get away, even on the final day. He had a four-shot lead with four holes remaining in the 2012 British Open when it all went wrong — four straight bogeys — and Ernie Els walked off with the claret jug. Thats a distant memory for Scott, who takes that green jacket from Augusta National with him just about everywhere he goes. "Seven shots over two days is not enough," Scott said. "I dont think you can ever be enough in the lead, to be honest." DIVOTS: Ryo Ishikawa had a 74 and was among those in the group at 5-under. The Japanese star has been working hard on his English.
