KEY BISCAYNE, Fla. - Even with his surgically repaired back still nowhere near perfect, defending champion Andy Murray needed only 73 minutes to beat Jo-Wilfried Tsonga 6-4, 6-1 at the Sony Open on Tuesday and set up a quarterfinal with Novak Djokovic. "My game is getting there," said Murray, the No. 6 seed, who acknowledged he was dealing with a sore back. "The last six sets Ive played, very high-level tennis, very few errors." Hell need to keep it that way against Djokovic, who eased past Tommy Robredo 6-3, 7-5. The second-seeded Djokovic even gave back a point in the second set. A groundstroke from Robredo clipped the baseline and Djokovic couldnt handle it, but the ball was erroneously called out. After a review showed the ball was in, the point was ordered to be replayed. Djokovic shouted "Its OK, its OK" as the fans applauded his sportsmanship. "For me, its something that is part of the sport, fair play," Djokovic said. "I expect everybody else to do the same. Of course, not everybodys the same, but for me, thats something thats normal. Just a normal, natural reaction." Top-seeded Rafael Nadal downed 14th-seeded Fabio Fognini 6-2, 6-2. Nadal has dropped a total of nine games in six sets so far in this tournament. Singles players with a combined 66 Grand Slam victories were in action Tuesday, including Roger Federer — a winner of 17 of them himself. And he looked very much like the Federer of old, needing only 49 minutes to beat ninth-seeded Richard Gasquet 6-1, 6-2. "Look, things went well out on the court today," Federer said, clearly understating matters. Federer, the No. 5 seed, had 25 winners to Gasquets eight, converted five of his six break chances and won 92 per cent of his first-serve points in the second set. Next up for Federer is 20th-seeded Kei Nishikori, who upset No. 4 David Ferrer 7-6 (7), 2-6, 7-6 (9). Ferrer had beaten Nishikori in the same round at Key Biscayne a year ago, their most recent meeting before Tuesday. No. 22 Alexandr Dolgopolov of the Ukraine also pulled off an upset, topping third-seeded Stanislas Wawrinka 6-4, 3-6, 6-1 to reach the quarterfinals. The last American in the mens draw was ousted when 10th-seeded John Isner lost to No. 7 seed Tomas Berdych 6-3, 7-5. On the womens side, Maria Sharapova rallied from a break down in the first set to oust Petra Kvitova 7-5, 6-1 and earn a spot in the semifinals. Shes been a finalist at Key Biscayne five times, but never the champion. "I love the energy here," she said. The fourth-seeded Sharapova, who needed three-setters to get through her two most recent matches at Key Biscayne, feasted on 30 unforced errors by the eighth-seeded Kvitova. Sharapova won 11 of the final 13 games and moved into a semifinal matchup with Serena Williams, the defending champion who won 62 of 100 points in her 6-2, 6-2 romp over fifth-seeded Angelique Kerber. Williams broke Kerber twice in each set, faced only one break point and held a more than 2-to-1 advantage in winners. "When youre playing champions, you like to play your best," Williams said. "She always gives me her best. ... I love playing her. I really do. It doesnt matter what surface. Shes one of my favourite people to play." Sharapova said she was eager to face Williams again. "Its no secret that shes been a big challenge of mine, an opponent that obviously I would love to beat," Sharapova said. Also, former No. 1 Martina Hingis teamed with Sabine Lisicki to reach the doubles quarterfinals. And foot and vehicle traffic outside the tennis centre was briefly halted during the night session when a suspicious backpack was found near the main gate, but Miami-Dade police responded and quickly determined there was no threat.

After Mondays comments by Coach Claude Noel that its work first and skill second, and that more “A” games are needed, the Jets responded with a 47-shot effort. If not for terrific goaltending by Braden Holtby the Jets would have had two points in regulation.Its New Years Day and Jack Armstrong is here with his first thoughts of 2015 on the high-flying Portland Trail Blazers, the Toronto Raptors current road trip, the return of Kevin Durant, Jared Dudleys impressive first year in Milwaukee and the injury to Al Jefferson. Greetings from San Francisco! I can think of a lot worse places to be, thats for sure. Happy New Year! My Best Wishes to each of you and I hope you have a wonderful 2015. FIVE QUICK NBA THOUGHTS: 1. PORTLAND TRAIL BLAZERS: Im really impressed. They have a very nice team and a big factor that jumps out at me is that they have four above-average perimeter defenders in Damian Lillard, Steve Blake, Nicholas Batum and Wesley Matthews. All do a solid job in making you earn everything you get. Not many teams in the league that have a perimeter corps that prides itself on being two-way players. This team is sound on both sides of the ball. 2. GREAT CHALLENGES FOR THE RAPTORS: It was a sensational game in Portland on Tuesday night between the #2 and #3 teams in the NBA in overall record. There was a terrific atmosphere and, even though Raps ran out of gas late, it once again proved to me that theyre growing as a team and are capable of playing with anyone. Another awesome test awaits on Friday against the top team in Association and the Golden State Warriors. I cant wait. These are the games that Raptors fans having been waiting to experience for years. Enjoy it - win or lose. Its all part of the journey of this team figuring out how to become a contender. Its not there yet, but this is what shapes aand tests you for future improvement.ddddddddddddThere are many more ups and downs coming, but its nice to have true meaning each time game night arrives. 3. KEVIN DURANT (Thunder): A quiet night for Durant against the Suns on Wednesday with only 44 points, 10 boards and with seven assists. Eh, the guy is decent. The Thunder are only a game-and-a-half back from the final playoff spot in the West. If these guys stay healthy, watch out. Imagine being a top-three seed and having a sensational season and then being stuck having to play the Thunder as a bottom-three seed. Itll be fun to watch the elite Western teams in early April try to avoid a first-round match-up with these guys. Scary opponent. 4. JARED DUDLEY (Bucks): Ive always been a huge fan of his. Dudleys a no-frills, hard-working guy, who gets a lot out of his abilities. He does whatever you need to win. The Bucks second unit has been a huge plus this season and a big reason is his team-first approach. A winning player, Dudleys bounced back from a tough year and Im sure the Clippers miss him. 5. AL JEFFERSON (Hornets): What a nightmare season. Josh McRoberts bolts to Miami (and they miss him), Lance Stephenson has been a bust, chemistry has been shaky and now the big fella is going to miss some time with a groin injury. Jeffersons a force inside that you cant replace. Its a tough blow for Coach Steve Clifford, one of the talented young coaches in our game. Its been a brutal year for Charlotte after such a fun one last season. Winning, health and chemistry are a very fragile thing. ' ' '
