MELBOURNE, Australia - The injuries mounted at the Australian Open on Tuesday, although for the most part, players coped with the oppressive heat. Nike Air Max Thea España . No. 13-seeded John Isner and No. 21 Philipp Kohlschreiber were among six players who dropped out of the tournament on Tuesday, joining No. 12 seed Tommy Haas and two other players who withdrew on Monday. Despite temperatures reaching 42 Celsius (108 Fahrenheit) during the afternoon and a hot breeze gusting over Melbourne Park for most of the day, none of the withdrawals were apparently linked to the temperatures. Isner retired from his match against Slovakias Martin Klizan with a lingering ankle injury that he said got progressively worse at the Hopman Cup event in Perth and a tournament he won in Auckland, New Zealand, over the past two weeks. "I know movement is not the best part of my game," the 2.08-meter (6-foot-10) American said, "but at a certain point Ive got to be able to move without pain and I wasnt able to do that today." He withdrew before last years Australian Open with an injury, as well. "I thought I had a good shot at playing this match and winning this match and I pulled out," he said. "I could have done the same last year, but I went home." The other seeded player in his section of the draw, Philipp Kohlschreiber of Germany, withdrew before his scheduled first-round match against Slovenian Aljaz Bedene with a left hamstring injury. He was replaced in the draw by Frenchman Stephane Robert, a lucky loser from qualifying, who defeated Bedene to reach the second round. Hometown favourite Bernard Tomic later retired with a left leg injury after losing the first set against top-seeded Rafael Nadal 6-4, much to the astonishment of the Rod Laver Arena crowd, who initially booed him. "It was very difficult for me to say sorry to the crowd," he said. "I dont think they quite knew what was wrong with me." Tomic suffered the injury in training on Monday. Czech veteran Radek Stepanek also retired from his match against Slovenian Blaz Kavcic with a neck injury while leading 7-6 (3), 6-4, 1-6, 0-2 after nearly three hours of play. A few other players struggled in the heat on Tuesday, but finished their matches. Canadian qualifier Frank Dancevic said he blacked out during his 7-6 (12), 6-3, 6-4 loss to No. 27-seeded Benoit Paire of France. Dancevic, who required medical attention during the second set, questioned the wisdom of not suspending matches during the torridly hot conditions. "I dont think its fair to anybody, to the players, to the fans, to the sport when you see players pulling out of matches and passing out," he said. "I think its definitely hazardous to be out there. Its dangerous." Nike Air Max 93 Baratas .Ryan Anderson had 14 points for the Pelicans, who trailed 78-63 after three periods before trimming the deficit to 86-83.

In fact, the first-year head coach said hes a little concerned about his teams focus as the playoffs approach. "We havent been the same team the last two games," Clifford said. "Whether we exhaled after clinching (a playoff spot), or whatever it is, I dont know. Whatever it is, we have two games to get it back." The Bobcats held on to beat the Philadelphia 76ers 111-105 on Saturday behind 29 points and 12 rebounds from Al Jefferson, but it was far from an impressive victory. The win came on the heels of a costly loss at Boston Friday night that dropped the Bobcats back to seventh place in the Eastern Conference standings. Charlotte (41-39) remains one game behind Washington in the race for the sixth seed with two games left. The Wizards defeated Milwaukee 104-91 on Saturday night. Jefferson said the Bobcats need to find their mojo with two tough games coming up to close the season — at Atlanta on Monday night and at home against Chicago on Wednesday. "I thought (the loss to Boston) would wake us up for this game, but I dont know whether it was a back-to-back, three games in four nights or what," Jefferson said. "... You could tell we were low energy. But we found a way to win, so thats the positive side of it." You cant blame Jefferson for the teams sudden funk. He has at least 20 points and 10 rebounds in each of the last six games, a franchise record. Luke Ridnour, starting in place of injured point guard Kemba Walker, had 12 points and eight assists in his first start for Charlotte. Clifford said he expects Walker to return from a groin injury Monday night. But he expressed plenty of confidence in Ridnour to handle the role when needed. "Were organized when Luke is in there," Clifford said. "He gets guys into their right spots. He has a high basketball IQ and he knows the NBA game." Michael Carter-Williams had 23 points and eight assists to lead the 76ers, who havee lost 16 of their last 17 games on the road. Zapatillas Air Max 95 Baratas. The same problem that haunted the Bobcats in their loss to Boston — poor defensive effort — hurt them early on against the 76ers. Philadelphia took a 59-56 at the break despite the Bobcats shooting 62 per cent from the field in the first half. Charlotte would begin to take control late in the third quarter, opening a double-digit lead behind a pair of 3-pointers from Ridnour and Chris Douglas-Roberts and some solid inside play from Cody Zeller. But ultimately the game came down to Philadelphias inability to stop Jefferson in the low post. Jefferson is averaging 26.1 points and 13 rebounds over the past six games and he showed again why hes an All-NBA team candidate. Jefferson had his way early on scoring 21 points in the first half on 10-of-13 shooting. He used his old-school style of play to make defenders Henry Sims and Byron Mullens look foolish at times by getting them to leave their feet with pump fakes, leading to easy up-and-under layups. "Hes got one of the best head fakes in the game, so its tough to defend him," Mullens said. Philadelphia got 16 points from Thaddeus Young and 15 from Henry Sims, but it wasnt enough for the leagues second-worst team. Still, it was a better showing than last week when the 76ers lost by 30 to the Bobcats on their home floor. At one point, the 76ers fell behind by 16, but closed to within four in the final minute — but were unable to take the lead. "It was entirely different," coach Brett Brown said. "When you look at the last time we played this team, it was as good an effort as anybody has played on our home court. They shot it and they guarded. Tonight we blinked a little in the third, but we found a way to get back in it in the fourth." NOTES: Philadelphias Jarvis Varnado was a late scratch with a right heel injury. ... The Bobcats have won 24 games at home, the second-most in franchise history. .. The Bobcats are 18-9 since the All-Star break, including 14-6 in their last 20 games. ' ' '
