RIO DE JANEIRO — Ashton Eaton retained his title by tying the Olympic record in the decathlon Thursday night.

Eaton, the world champion, finished with 8,893 points, incredibly matching exactly the Olympic record after 10 lung-busting events. He finished third in the final event, the 1,500 meters, to win gold from Kevin Mayer of France on 8,834 points. Damian Warner of Canada took the bronze.

Eaton has won successive Olympic and world titles to confirm his status at the best all-around athlete in the world.
