LONDON - Ryan Lochte and Sun Yang were among the few who weren't concerned about getting wet when heavy rain saturated London Olympic Park on Sunday.

After a week of sunshine, rain and the forecast of hail on the second day of competition affected the start of tennis on the lawn courts at Wimbledon and made for slippery conditions in the women's cycling road race.

It didn't seem to bother the swimmers. Lochte had the second-fastest time in qualifying for the 200-meter freestyle, the morning after his stunning win in a 400-meter individual medley final that will be famous for the fact Michael Phelps missed a medal.

Phelps won an unprecedented 8 golds at the Beijing Olympics, but now can't win any more than six in London. China's Sun is on track for a second gold medal after leading qualifiers in the 200 freestyle in 1 minute, 46.24 seconds the morning after his victory in the 400 freestyle.

While the weather was bad, there were other blights: a female gymnast from Uzbekistan was provisionally suspended after failing a doping test, the second case of the games. The IOC says Luiza Galiulina tested positive for the diuretic furosemide on Wednesday.

It came a day after the IOC expelled Albanian weightlifter Hysen Pulaku from the games after he tested positive for the banned steroid stanozolol on July 23. And hundreds of fans wanting to see New Zealand, Brazil, Belarus and Egypt were stranded in London or forced to sit on the train floor Sunday as service operators supplied only two morning London-to-Manchester services in time for the noon kickoff of the New Zealand-Egypt match in Manchester, 200 miles (320 kilometers) northwest of London.
