BOXING: Floyd Mayweather has confirmed he will put his unbeaten record on the line in a light-middleweight unification world title fight against Saul 'Canelo' Alvarez later this year.
Mayweather, widely regarded as the best pound-for-pound boxer on the planet, moved to 44 wins from as many fights after a comfortable points triumph over Robert Guerrero for the WBC welterweight title earlier this month.
A bout with Mexican Alvarez, who is also undefeated from 43 contests, has been steadily building momentum and Mayweather confirmed he will challenge the Mexican WBC and WBA light-middleweight champion on his official Twitter account.
"I chose my opponent for September 14th and it's Canelo Alvarez.
"I'm giving the fans what they want. It will be at the MGM Grand," Mayweather said.
Several media outlets in the United States have reported the bout will be at a catchweight of 152lb – two pounds below the light middleweight limit – but Alvarez will still put his titles on the line as will Mayweather, who remains the WBA's 'super' champion after outpointing Miguel Cotto last year.
WILLIAMS MOVE TO BENZ
FORMULA ONE: Williams have confirmed they are to change engine supplier from next year as the Grove-based marque are to switch to Mercedes-Benz.
With new engine regulations coming into force from 2014, with 1.6-litre V6 turbo-charged power units replacing the current 2.4-litre V8s, Williams have taken the opportunity to oust Renault and bring in Mercedes.
Williams only joined forces at the start of last season with Renault, the French manufacturer helping to power Pastor Maldonado to victory in the Spanish Grand Prix, which ended a seven-and-a-half-year drought for Williams.
There had been hopes of a return to the glory years of the 1990s when Williams won five constructors' titles in six years from 1992-1997, along with four drivers' championships, with Nigel Mansell, Alain Prost, Damon Hill and Jacques Villeneuve at the wheel.
But since that relationship ended in 1997, Williams have struggled to find a consistent, reliable partner, with Mercedes to become their seventh different supplier in what will be 18 seasons.
MO IS NOT THE MERRIER
ATHLETICS: A stomach virus will keep British double Olympic champion Mo Farah out of a dream match-up with Ethiopian world record holder Kenenisa Bekele over 10,000 metres at the Prefontaine Classic tonight.
Farah instead will run tomorrow in the 5,000 metres where he is also the London gold medallist, facing training partner and Olympic 10,000 metres silver medallist Galen Rupp.
