SHANGHAI -- American sprinter Justin Gatlin's preparations for the Rio de Janeiro Olympics got off to a solid start with a commanding win in the 100 meters at the Shanghai Diamond League meet on Saturday.
Olympic 800 champion David Rudisha of Kenya faded on the final straight and finished fifth after a poor start he blamed on field competitors crowding the track.
Gatlin easily won the 100 in 9.94 seconds, several strides ahead of Qatar's Femi Ogunode in second. His main rival in Rio, Olympic and world champion Usain Bolt, did not compete in Shanghai.
Rudisha, meanwhile, was passed by countryman Ferguson Cheruiyot Rotich, who won the 800 in 1 minute, 45.68 seconds.
