Germany's Leo Neugebauer is the leader in the men's decathlon at the Paris Olympics with three events to go, reclaiming top spot with a solid discus throw after briefly dropping to third after Saturday's opening 110-metres hurdles race.
The 24-year-old who has the world's best score this season, set in winning his second consecutive NCAA title for the University of Texas, has 6 500 points after seven events.
Canada's reigning Olympic champion Damian Warner, who briefly led after a solid hurdles race, is second with 6 428, while 22-year-old Norwegian Sander Skotheim is third (6 326).
The remaining events are the pole vault, javelin and 1 500m.
The 34-year-old Warner, who became the oldest Olympic decathlon gold medallist three years ago in Tokyo, climbed from fourth to first in the 110m hurdles to kick off day two, with a time of 13.62, while Neugebauer dropped to third, with only 25 points separating the top three.
But the 24-year-old German reclaimed the lead with a throw of 53.33m in the discus, one of his strongest events, while Warner hurled it 48.68m.
Grenada's Lindon Victor let fly a 53.91m toss, the best discus throw by a decathlete in Olympic history.
The field is missing France's world record-holder Kevin Mayer and reigning world champion Pierce LePage, who both withdrew due to injuries.
