Japanese teenager Yoshihide Kiryu has equalled the World junior 100m record* with a 10.01 (0.9m/s) clocking at the Mikio Oda Memorial in Hiroshima.
His record-breaking performance -- which ties Darrel Brown's World junior record from 2003 -- came in the heats, and he followed it up in the final with a wind-assisted 10.03 (2.7m/s).
Kiryu's time makes him the fastest ever 17-year-old over 100m. It is also just 0.02 off Samuel Francis's Asian senior record and 0.01 away from Koji Ito's Japanese senior record.
Kiryu -- who will still be a junior through to next year -- exploded on to the scene last year, twice breaking the World youth 100m best; first with 10.21 in October, then with 10.19 one month later.
His 10.01 clocking in Hiroshima was his first race of 2013 and puts him at the top of this year's senior world lists.
