Rain halts play at Valhalla

Torrential rain forced play to be suspended just 20 minutes into the second round of the US PGA Championship.

Having got underway at 7:30am, the first group of joint leader Ryan Palmer, Shane Lowry and Bob Sowards were still on the first green when the decision was taken to call a temporary halt to proceedings.

Members of the greenkeeping staff at Valhalla had been attempting to clear water off the green, but that proved an impossible task as the rain intensified as the morning wore on.

The forecast for the rest of the day will be a concern for tournament organisers, with Tiger Woods predicting on Thursday that, as one of the later starters, he might not complete his second round until Saturday.

Palmer shared the lead on six under par alongside fellow American Kevin Chappell and Lee Westwood of England.

New world number one Rory McIlroy was a shot behind in a group that also included Henrik Stenson, Chris Wood, Edoardo Molinari and Jim Furyk.

Woods, who had declared himself fit just days after withdrawing from the final round of the WGC-Bridgestone Invitational with a back problem, had struggled to an opening 74.
