(CNN) -- Sweden's Daniel Chopra holds the clubhouse lead at the Singapore Open as lightning again disrupted play with more than half the field failing to finish their second rounds, including first round leader Ian Poulter and world number two Phil Mickelson.
Chopra is on seven-under-par 135 after firing a bogey-free 65 with Australia's Andrew Dodt and China's Liang Wenchong two shots further back.
But Englishman Poulter is also seven-under after three holes having picked up two early birdies, while Taiwan's Chan Yih-Shin is on the same score after seven holes while South Africa's Ernie Els is a shot further back after three.
Three-time Major winner Padraig Harrington played a gruelling 27 holes, recovering from an appalling start to finish strongly on the final nine to stay in the hunt, eight shots off the pace.
Mickelson is also eight behind the leaders after four holes of his second round, shooting pars after dropping a shot on the first.
Chopra, twice a winner on the PGA Tour, told reporters he felt his game was finally coming together after a disappointing year.
"Of all the years that I have been playing in the United States I've under-achieved most this year," he said. "But I think I have been playing well and I've always believed that good things were just around the corner."
Meanwhile, Thai Chapchai Nirat rocketed up the leaderboard when he sunk a hole-in-one at the eighth. It was the 29th hole-in-one on the European Tour this year and the ninth in Asia.
Chapchai is four-under-par for the tournament having completed his second round.
