DELRAY BEACH, Fla. -- John Isner held off an upset bid by Dudi Sela of Israel on Thursday night to advance to the quarterfinals of the Delray Beach Open after No. 3 seed Kei Nishikori of Japan exited the tournament because of a left hip injury. The second-seeded Isner squandered four match points in the third set after leading 4-1, but the 6-foot-10 American rallied from a 5-2 deficit to prevail in the tiebreaker for a 3-6, 6-1, 7-6 (5) victory that earned him a spot in the quarterfinals for the third consecutive year. "More times than not, when Im up 4-1, I close it out," said Isner, who is 5-0 in his three-set matches this season but is playing in his first tournament since exiting the Australian Open with an ankle injury last month. "It definitely didnt need to go to 5-5 when I was up 4-1. I put a lot of stress on myself when I do that." The world No. 13 will face American qualifier Rhyne Williams on Friday night. Williams ousted wild-card Marcos Baghdatis of Cyprus 6-7 (7), 6-4, 6-2 in Thursdays nightcap to reach his second ATP quarterfinal. Nishikoris bid to win his second consecutive ATP title came to an abrupt halt Thursday afternoon when the top-ranked Asian was forced to retire during the first set of his second-round match because of a left hip flexor injury. Nishikori was trailing Teymuraz Gabashvili of Russia 4-2 when he decided to stop the match. He said that he experienced discomfort for the first time during his first-round win Tuesday in which he stretched his win-loss record this season to 12-2. "I tried to play, but if youre not 100 per cent, its tough," said Nishikori, who is ranked No. 15 in the world and was coming off a win in Memphis last week. "I couldnt do anything today. Its going to take some time to recover. Its shocking this happened, especially since Ive been playing well." Gabashvili advanced to the quarterfinals on Friday and will face No. 7 seed Marin Cilic of Croatia, who defeated American wild-card Ryan Harrison 6-3, 6-4. Samuel Groth and Max Mirnyi advanced to the doubles semifinals with a 7-6 (5), 6-4 win against Americans Sekou Bangoura and Vahid Mirzadeh. Harrison and fellow American Jack Sock filled out the final spot in the doubles semifinals with a 6-4, 7-5 win against Santiago Gonzalez and Scott Lipsky. Nike Air Max 90 Günstig Schweiz .

The Stars enter the opener of a three-game homestand locked in an 0-2-2 slide and the four-game skid comes directly on the heels of a 9-2-0 run from Dec. 6- Jan. 3. The club sits six points out of a playoff spot in the highly competitive Western Conference. However, Dallas has won five straight and seven of nine over the Senators. Ottawa has dropped three in a row and five of the past six meetings at American Airlines Center. Tonight marks the first time Stars forward Jason Spezza will face his former team. Spezza compiled 687 points (251 goals, 436 assists) over 11 seasons and 686 games with Ottawa, but he requested a trade from the Sens last spring and was eventually dealt to Dallas on July 1. Spezza was traded to the Stars along with forward prospect Ludwig Karlsson, while Ottawa received forwards Alex Chiasson, Alex Guptill, Nicolas Paul and a second-round pick in 2015. The 31-year-old Spezza is third on Dallas this season with 29 points off seven goals and 22 helpers. He signed a four-year extension with the Stars in November, keeping him under contract in Dallas through the 2018-19 season. It was nice to catch up. I saw some of the guys yesterday and will catch up with a few more guys today, Spezza said after Mondays practice. I think it is different when it is on your terms and in your rink. It will be different when I go back to Ottawa. Spezza and the Stars are scheduled to visit the Senators on Jan. 29. Dallas may ask for more than usual from Spezza as it may have to face Ottawa tonight without the help of captain Jamie Benn and fellow forwards Vernon Fiddleer and Tyler Seguin, who are all questionable for Tuesday.dddddddddddd Benn is dealing with an undisclosed injury, while Fiddler left Saturdays loss against Colorado with a lower-body issue. Seguin, meanwhile, was sent home from Mondays practice with an illness. Seguin is leading Dallas in goals (26) and points (48), while Benn is second in team scoring with 36 points on 12 goals and 24 assists. The Stars fell 4-3 in Denver on Saturday, as Matt Duchene picked up the deciding goal for the Avalanche early in the third period. Brett Ritchie, Colton Sceviour and Ales Hemsky scored for the Stars, while Kari Lehtonen stopped 26 shots in defeat. Lehtonen is expected to start tonight and owns an 8-5-0 record and 2.75 goals against average in 15 career games against the Senators. Ottawa enters tonight eight points out of a playoff spot in the East, but it was able to halt a three-game slide with Saturdays blowout win in Arizona. Craig Anderson made 31 saves, and the Sens scored five unanswered goals to top the Coyotes, 5-1. After Mikkel Boedker put the Coyotes on top early in the game, Milan Michalek and Clarke MacArthur scored first-period goals to give the Senators the lead for good. Ottawa also got goals from Mike Hoffman, Cody Ceci and David Legwand to improve to 1-1-1 on a four-game road trip that ends tonight. The Sens are just 9-11-4 as the guest this season. We finally got rewarded for our effort, Senators head coach Dave Cameron said. It feels good. Robin Lehner will get the start in net for Ottawa. He is 0-1-1 with a 2.88 GAA in his career against Dallas. After tonight, the Senators will close January by playing five of six on home ice. Ottawa will begin a brief two-game homestand Thursday against Montreal. ' ' '
