Rafael Nadal has warned tennis chiefs that the sport faces future troubles if equipment evolution continues to make speed and power dominate skill and tactics. On the eve of his opening match at the Miami Open, the 14-time Grand Slam singles champion said changes are needed to counteract taller and stronger players using modern racquet technology to make quick work of points and matches.The sport in general needs to improve in all aspects, Nadal said. The players today are taller than before. The racquets hit the ball harder than before. Same time, its true that nothing changed in our sport in terms of rules, how high is the net, everything.People get emotional when the points are intense, long. If every time we make that happen less often, its obvious our sport can be in trouble for the future.The 29-year-old Spanish left-hander said tennis must adapt for future generations to enjoy it as much as past ones have.Tennis has been tremendously successful for a long time. The sport is healthy. But its obvious at the same time we need to move, to predict the future, Nadal said. Nadal says Novak Djokovic deserves his current dominance Im not talking for my generation but for the next generation. The people like the drama, the rallies. I dont remember amazing matches that was only one serve and one shot.The matches that people remember most are matches that are slow matches with unbelievable points and the applause of the people or the emotions of the people are not only with one serve and one shot.Nadal said it is important for tennis to develop stars and rivalries, such as he has enjoyed with once-dominant Roger Federer and with Novak Djokovic, whose 11 career Grand Slam titles include four of the past five contested. Highlights of the semi-final clash at Indian Wells between Novak Djokovic and Rafael Nadal In my opinion, its not good if win a tournament every week a different player. People arrive at the tournament and nobody knows who are the favorites, Nadal said.Its difficult because the people need to support one player, so you need the stars. To create the stars you need players that have been there for a long time.At the same time its good to have a combination of styles, different players that fight for the important things and one or another can win. That has happened the last 10 or 12 years.Its obvious now its better for Novak. For last year and a half, two years, one is dominating. Maybe too much. But he deserves.Nadal, who has struggled with knee injuries for years, went without a Grand Slam title last year for the first time since 2004 but is not looking toward the end just yet.Im happy doing what Im doing. I enjoy playing my sport, he said. Its about love for the game, about passion for what Im doing and Im going to be here until Im unhappy doing what Im doing.Watch the Miami Open on Sky Sports 3 HD - your home of tennisBy purchasing a Sky Sports Day Pass for £6.99 or Sky Sports Week Pass for £10.99, you can enjoy access to all seven Sky Sports channels and watch on a TV with a NOW TV Box or on a range of devices.

It was the quickest three-goal sequence in Olympic history, with the latter two coming just eight seconds apart.

His response from Victory Lane, too bad. Busch raced to his second victory of the weekend at Dover, taking the checkered flag Saturday in the Nationwide Series race to set himself up for a tripleheader sweep. "I do it for the pure love of the sport and just wanting to be out there," Busch said. "Ill keep doing it as long as we can do it." Busch followed his dominant win Friday night in the Truck Series with another stellar run in Nationwide. He led 124 of 200 laps for his 66th career victory in NASCARs second-tier series. He has 134 wins spread over NASCARs three major series, though he has yet to win a Cup championship or marquee races such as the Daytona 500, Brickyard 400, Coca-Cola 600 or All-Star race. "Ive got a 134 of em now and none of them mean nothing," Busch said. "Hopefully, someday, the big ones come." Busch had a three-race sweep in 2010 at Bristol, which he called the highlight of his career. Hell start second behind pole-winner Brad Keselowski on Sunday in the 400-mile Sprint Cup race. He has one Cup victory this season. "We unloaded fast and I think well be OK tomorrow," Busch said. Former Daytona 500 champion Trevor Bayne was second. Bayne finished strong a week after he reached a deal to race fulltime next season for Roush Fenway Racing. Joey Logano, Matt Kenseth and Chase Elliott round out the top five. Series points leader Regan Smith was 10th. Logano, the pole winner, had won the last four Nationwide races at Dover and would have tied a Nationwide record for consecutive wins at the same track with a victory. "All good things must come to an end and weell give it another shot in the fall," Logano said.dddddddddddd "Maybe a couple of years later well be sitting here going for five again." This race belonged to Busch. The only driver to sweep a weekend, Busch has been in this position before, but is just 1 for 8 in Cup races after winning the first two. "It seems like the last one is always the hardest one," he said. "Thats due to just the competition." Busch was annoyed after rough practice and qualifying sessions left him feeling as if he didnt have the car to win. Once the green flag dropped, Busch was behind the wheel a No. 54 Toyota he called "awesome." "I didnt think it was, but it was," he said. "I never got the feel I was looking for during practice." Busch, who won for the third time this season, found it when it mattered on the mile concrete track. His brother, Kurt, failed last weekend in his attempt to complete The Double -- drive all 1,100 miles of the Indianapolis 500 and Coca-Cola 600 on the same day. Kyle Busch hoped he could complete his Triple, though the Cup race is the traditional roadblock in his date with racing history. Busch also was the first driver to win the Truck and Nationwide race at Dover on the same weekend. Busch and Brad Keselowski own Truck teams, and NASCAR star Dale Earnhardt Jr. owns a Nationwide team. And with sponsorship key to funding those operations, corporations often agree to sponsorship deals with the guarantee that the driver/owners will get behind the wheel in a handful of races or more. Tracks, television rights holders and NASCAR also all benefit from the draw of racings top drivers. "I know theres a lot of naysayers that say I dont belong or shouldnt be there," he said. "Until the rules change ... Ill keep running." ' ' '
