DUBAI, United Arab Emirates -- Novak Djokovic opened the defence of his Dubai Championships title with a straight sets victory over Denis Istomin, while second-seeded Juan Martin del Potro had to retire from his first-round match on Tuesday. Top-seeded Djokovic, who is making only his second appearance this year after reaching the quarterfinals of the Australian Open, was a 6-3, 6-3 winner over 54th-ranked Istomin of Uzbekistan. "It wasnt as easy as the scoreline indicates," said Djokovic, who has won in Dubai on four occasions. "I needed to work for my games. "Having not played for more than four, five weeks, an official match, obviously it takes its toll on the court." Djokovic saved all four break points he faced on serve and broke Istomin three times -- in the third and ninth games of the first set and in the second game of the second set. Del Potro was not so fortunate, being forced to retire against Somdev Devvarman of India after losing the first-set tiebreaker 7-6 (3). Since winning the Sydney title last month, Del Potro has been struggling with a left wrist injury that has conjured up memories of similar pain he experienced in his right wrist four years ago. In 2010, the year after he won the U.S. Open, he played only three tournaments before and after surgery on his right wrist. Del Potro was fighting back tears in Dubai when he came to talk to the media after his retirement. "I dont feel really well," he said. "My wrist is hurting a lot and everybody knows what happened to me four years ago with my other wrist. "It was really tough to play today. I tried everything. I cannot be the player I would like to be." Having felt the pain in his left wrist during the Australian Open, Del Potro went at the end of January to consult with Dr. Richard Berger, who performed his right wrist surgery at the Mayo Clinic in Minnesota. The doctor recommended a course of physical therapy. Asked if he would have kept playing if he won the first set, Del Potro said: "I dont think so, no. It was hurting too much." Devvarman, a wild card who won a challenger in New Delhi last week, hit a service winner on his third set point in the tiebreaker. That proved to be the final point of the match. "Its unfortunate, especially for a guy like him," Devvarman said. "I realized he wasnt comfortable hitting backhands and I tried to make him hit as many as I could, and he wasnt really hitting over it so I knew he wasnt happy." Third-seeded Tomas Berdych extended his winning streak to eight matches with a 6-3, 6-4 win over Romanian qualifier Marius Copil. Berdych, who reached the final in Dubai last year, won the Rotterdam title two weeks ago. Fifth-seeded Jo-Wilfried Tsonga of France secured a 6-2, 6-4 win over Victor Hanescu of Romania.

The former Tampa Bay Lightning star got his wish when he was dealt to the New York Rangers on NHL trade deadline day. He then got into the lineup with his new team right away, but wasnt able to celebrate his first home win on Broadway. Tyler Bozak scored on a penalty shot and then got the winning goal 1:51 into overtime to lift Toronto to a 3-2 victory over the Rangers on Wednesday night after the Maple Leafs squandered a two-goal lead in the third period. "Tonight was a gutsy comeback," St. Louis said. "Unfortunately we didnt get the extra point, but I was happy to come here and just break the ice." Bozak got to a loose puck in front that bounced past Rangers defencemen Dan Girardi and Ryan McDonagh and slammed a shot past Henrik Lundqvist to snap the Maple Leafs three-game losing streak (0-1-2) and stretch New Yorks skid to three (0-2-1). Lundqvist slammed his stick on the glass as he left the ice and was still aggravated when he got to the dressing room. "Every point is important right now. Its annoying the way it ends," he said. "We played really well and worked ourselves back into this game. Its a big frustration right now to not come out of it with two points." Toronto built a 2-0 lead on Bozaks second-period goal and Nazem Kadris tally in the third. The Rangers tied it on short-handed goals by McDonagh and Dominic Moore 1:19 apart. "That was tough," Bozak said of the Rangers rally. "Just have to play well on the power play. We played well for the most part. Made better decisions, just got lackadaisical for a bit." Lundqvist bounced back from two straight losses in which he gave up 10 goals, and finished with 26 saves. Torontos Jonathan Bernier had dropped two straight after regulation -- allowing nine goals in the process -- before sitting out Mondays loss against Columbus. He stopped 35 shots. The Rangers got even by scoring twice on the first power play they gave up in two games. McDonagh made it 2-1 at 5:34 with his 10th goal, and Moore tied it when he finished a 2-on-1 rush with Derek Stepan. It was the second time in four games Toronto allowed two short-handed goals on one power play. "Aside from those two minutes on the power play, we played a strong game," Kadri said. "We got the result we wanted, the two points. "We just to have to clean up the powerr play and well be better, but were all pleased with the overall good job we did.dddddddddddd." That was enough to prevent St. Louis from being a winner in his first Rangers game. St. Louis was acquired Wednesday morning from Tampa Bay in the rare swap of team captains that sent New Yorks Ryan Callahan to the Lightning. St. Louis, whose jersey was flying off the racks in the team store at Madison Square Garden before the game, got the chance to wear his own just hours after being dealt. "I always felt if I was going to leave Tampa, the first place Id want to play would be in New York," St. Louis said. "Its been in the back of my mind for a long time, but I wouldnt trade those 14 years in Tampa for anything." Just after Toronto killed a power play that carried over from the first period, James van Riemsdyk came out of the penalty box and sent Bozak in on a breakaway. Rangers defenceman John Moore hounded him from behind with his stick and prevented Bozak from getting a clean shot away. However, Bozak was awarded with a penalty shot at 1:44. Bozak skated in on Lundqvist, who came way out above his crease, and found space between his pads to score his 13th goal of the season on his first career penalty shot. The Maple Leafs next best scoring chance didnt register on the shot board as defenceman Jake Gardiners drive struck the crossbar and then the right post before bounding away. It was originally ruled a goal on the ice, but that call was overturned by video replay. Toronto managed only five shots in the second period, compared to nine for New York. The Maple Leafs doubled their lead at 2:00 of the third when Kadri steered in the rebound of Nikolai Kulemins shot. St. Louis got a nice ovation when he hopped over the boards for his first shift 38 seconds in, and created a surge of excitement when he fired a hard shot on goal from the top edge of the left circle. Bernier was sharp and stood tall following a handful of miscues by teammates in front of him, stopping 12 shots in the first period. Lundqvist was just as solid at the other end, denying all 11 shots that came his way. NOTES: The Rangers wont name a new captain this season. Instead, D Dan Girardi joined Marc Staal and Brad Richards as those wearing an A on their jersey. ... Cam Talbot was the winning goalie in the Rangers two victories over Toronto this season. The Maple Leafs avoided a three-game, season-series sweep. ' ' '
