Usain Bolt v Justin Gatlin could produce 'crazy' time

Usain Bolt and Justin Gatlin's rivalry can Martin St. Louis Jersey produce a "crazy" time at August's World Championships, says ex-British sprinter Darren Campbell.
Bolt, who set the world record of 9.58 seconds in 2009, ran two season best times of 9.87 at the Anniversary Games.
Campbell believes Bolt's performances at London's Olympic Stadium prove the Jamaican can challenge the year's fastest sprinter Gatlin.
"They both believe they can win gold. That makes it exciting," he said.
Campbell, a former world 100m bronze medallist, added: "Now Bolt's in shape, he has 100% belief. Gatlin definitely believes he can win and that's what potentially will bring out a crazy time in Beijng.
"Rivalries are important because it makes people dig deeper."
Injury and poor form meant Bolt had run just once over 100m in 2015 prior to Friday, a lacklustre 10.12 in Brazil in April.
But in wet conditions he twice dipped below 10 seconds for the first time this year, on the track where he won three of his six Olympic titles.
The 28-year-old secured victory in his heat with ease and Shaquille O'Neal Jersey while beating his rivals in the final was more of a challenge, he equalled his impressive qualifying time - the joint sixth fastest time of the year.
According to BBC Radio 5 live pundit Campbell, the two races this weekend confirmed Bolt - who withdrew from two Diamond League meetings this month with a pelvic problem - looked in "good shape".
"It's important people understand that the injury he had would be similar to having a car with one flat tyre," explained Campbell.
"Usain Bolt's strength is his stride and for him not to be able to get the stride length means he won't get rhythm so you can understand how that would play a big part in why his times were down.
"The performances were very impressive just because of the conditions, they were terrible. We do know the Olympic Stadium's track is quick, but you have to be in shape to put out that time.
"We saw that shift in gear he has when he gets http://www.authenticyankeesshop.com/authentic-2-derek-jeter-jersey.... 40m, when he starts to open up his stride, and it's still there. That first 30 to 40m he can work on. These final three weeks before the championships he will sharpen up, but Gatlin is a real threat."
Will Gatlin be worried?

American Gatlin, a two-time drug cheat, has established himself as the world's dominant male sprinter this year.
The 9.74 personal best he clocked in Doha in May continues to be the world-leading time, and he has gone under 9.8 four times in 2015 - 9.74, 9.75, 9.75, 9.78.
Campbell believes the criticism Gatlin continues to receive after returning to the sport following a second doping ban suggests the 33-year-old is not easily ruffled.
"Set aside what he's done with regards to the drugs, as a competitor, as a character, Gatlin doesn't let many things bother him and that's important as a sportsperson," added Campbell.
"I don't think he'll be scared. He's a real competitor, someone who can dig deep. He won't quit. He thinks he has the beating of Bolt.
"But I can now get excited about http://www.authenticbruinsshop.com/authentic-27-dougie-hamilton-jer... the Worlds because, before Friday, Gatlin was the red-hot favourite and that can be a bit boring."
