World and Olympic triple gold medallist Usain Bolt got his 100-metre season underway in a respectable 9.86 seconds at the Daegu Pre-Championships Meeting on Wednesday.
Bolt, who owns the world record of 9.58, was the only man under the 10-second barrier, with fellow Jamaican Michael Frater finishing second in 10.15. American Mike Rodgers came third in 10.18.
Another American Travis Padgett, who clocked 9.92 in the windy Doha Diamond League meet last week, could only manage fifth in 10.30, as the athletes got a feel for the stadium that will host the world championships next year.
Bolt's time contrasted to key rival Asafa Powell's 9.81 at Doha, where he was powered by a gusting desert wind. Both Powell and American Tyson Gay have made clear they are eyeing Bolt's world record this year.
Boston beat Orlando
Paul Pierce scored 28 points and Rajon Rondo with 25 as Boston took a 2-0 series lead by edging Orlando 95-92 in their NBA semi-final series on Tuesday.
