England's Ian Poulter slipped into a tie with Thomas Levet and Kodai Ichihara for the clubhouse lead before thunderstorms cut short play in the third round of the Singapore Open on Saturday.

Poulter, who finished up his second round in the morning with a seven-under-par 64 and a commanding five-stroke lead, faltered in the afternoon to shoot four-over through six holes.

Andrew Dodt and Liang Wen-chong were tied a shot off the lead while three others are tied two shots back.

Ernie Els joined three other players at five-under.

"There are so many guys close to the top of the leaderboard, within a few shots, so this tournament is nowhere near finished," Levet said.

"I'm looking forward to tomorrow because I love the battle."

The second round was completed on Saturday because of rain delays the previous two days. The third round is scheduled to finish Sunday morning.

Phil Mickelson was two-under after completing 15 holes of the third round while Padraig Harrington was two-over after eight holes.
