BEIJING -- Britain's Chris Hoy has won the men's keirin gold medal, adding to his country's staggering cycling medal haul at the Beijing Olympics.
With Hoy winning and countryman Ross Edgar taking silver on Saturday, 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 in which riders spend 5½ laps jockeying for position behind a pacesetting motorcycle that accelerates steadily before leaving the track and leaving the competitors alone on the track for the final 625 meters.
Earlier Saturday, in the men's 4,000-meter individual pursuit, Britain's Bradley Wiggins won his second straight Olympic gold medal, defeating New Zealand's Hayden Roulston in the final.
A three-time world champion in the event, Wiggins finished in 4:16.977, about 2½ seconds ahead of Roulston -- who eliminated American phenom Taylor Phinney in the quarterfinal round.
Britain's Steven Burke defeated Russia's Alexei Markov in the bronze-medal race.
Spain's Joan Llaneras won the men's points race Saturday, adding that gold to the one he claimed in the event at Sydney in 2000 and the silver won in Athens four years ago.
Llaneras finished with 60 points, just ahead of Germany's Roger Kluge, who wound up with 58 for the silver. Britain's Chris Newton won the bronze with 56 points.
Llaneras took control over the second half of the race, thrusting his arms into the sky at the finish.
The points race is a complex 160-lap event where riders seek points awarded in sprints every 10th time around the velodrome.
