SACRAMENTO, California, June 11 - Wallace Spearmon clocked 19.91sec, the fastest time in the world this year, to win the 200m at the US collegiate athletics championships on Saturday.
Kerron Clement won the 400m hurdles in another world leading time, 47.56sec as the university meeting produced a string of sizzling performances.
Clement’s time eclipsed the 47.62 run by Bershawn Jackson on May 22 in Carson, California.
Spearmon’s victory saw him regain the top spot on this year’s world list, after Tyson Gay posted a 19.93sec in the 200m semi-finals on Thursday. They are the only men to break 20 seconds so far this year.
Athens Olympic relay gold medallist Darold Williamson won the 400m title on Saturday, but he couldn’t improve on the world-leading 44.27 he clocked in Friday’s semi-finals.
That performance had the senior from Baylor University - which produced 2004 Olympic 400m champion Jeremy Wariner and before him 400m world record-holder Michael Johnson - looking forward to breaking 44 seconds in the final.
That didn’t happen, but Williamson took the title in 44.51.
Even that time was under the previous best of 2005, Wariner’s 44.53 at Carson.
