BEIJING (AP) -Britain's Chris Hoy won the men's keirin gold medal Saturday, adding to his country's cycling medal haul so far at the Beijing Olympics.

With Hoy winning and countryman Ross Edgar taking silver, the British already have eight cycling medals in Beijing, four of them gold.

Kiyofumi Nagai of Japan won the bronze.

The keirin is an eight-lap race, where riders spend 5 1-2 laps jockeying for position behind a pacesetting motorcycle that accelerates steadily before leaving the competitors alone on the track for the final 625 meters.
