Newly-crowned Olympic keirin champion Chris Hoy is primed for a semi-final clash with three-time world sprint champion Theo Bos as he looks for more gold in the men's sprint.

Scottish sprint king Hoy continued his bid for his third Beijing gold medal after coasting into the quarter-finals of the men's sprint Sunday.

Hoy, 32, beat a 12-year-old Olympic record for the 200 meters flying start in the qualifying round in a stunning time of 9.815 seconds.

He then saved precious energy by avoiding the costly repechages over two impressive rounds in which he dominated first Japan's Kazunari Watanabe and Russian Denis Dmitriev.

Teammate Jason Kenny, who is being groomed as Britain's future sprint king, made similar light work of his rivals, winning both his rounds.

Reigning women's world sprint champion Victoria Pendleton also qualified for Monday's quarter-final with a similarly dominant display.

Among the potential finalists to join the Englishwoman in Monday's quarter-finals were China's Guo Shuang, Australian Anna Meares, American Jennie Reed and Simona Krupeckaite of Lithuania.

The women's semis and finals are held, like the men's, on the final day of competition Tuesday.

Hoy now has what on paper looks to be an easy match in the quarter-finals, where he will meet Malaysian upstart Mohd Azizulhasni Awang, who got one of the loudest cheers of the night after a stunning move in his repechage heat.

The diminutive Malaysian booked his quarter-final place by pipping Stefan Nimke, a team sprint Olympic champion from Athens, by majestically lifting his wheel off the boards to push him just in front of the German at the finish.

Awaiting Hoy in the semis is Bos, who faces Mickael Bourgain in his quarter-final match.

Bos, who won silver in Athens behind Australia's Ryan Bayley, has had a disastrous keirin and sprint campaign so far.

After setting a time of just 10.381 for his flying 200 meters in qualifying, Bos said: "I'm ashamed. I'm starting to wonder if it was worth the price of the plane ticket to send me here."

That forced him into a fine display of tactical racing, which forced France's Kevin Sireau into the repechages and put him in the quarters.

"Finally there's something positive to say. I am super-happy, I have survived the day," said Bos. "Tomorrow I can race freely and against Bourgain I just have to go for it. Make sure I am tactically sharp, and then we'll see."

The other quarter-final pits 20-year-old Bolton boy Kenny against 21-year-old Sireau, who admits he has a special motivation to go further in his first Olympic campaign.

"I'm very motivated because I want to meet Bourgain in the final," said Sireau.

In the other quarter-final, Germany's Maximilian Levy will meet Dutchman Teun Mulder.

Australia's Ryan Bayley, who failed to make the closing rounds of the keirin, was again a pale shadow of the rider who majestically won keirin and sprint gold in Athens. As a result, he has left his future hanging in the balance.

"I am not sure if I want to continue or if I want to do something else," said the 26-year-old. "Professional cycling does not pay very well and I think it is time to pay back my girlfriend with some time instead of her waiting for me to come back from being away."
