England’s Lee Westwood was rewarded for his patience with a flawless four-under-par 68 to retain the clubhouse lead after the second round of the weather-hit Indonesian Masters on Friday.
The world No.3 made eight consecutive pars before carding four birdies for an 11-under-par 133 total at the $US750,000 ($A728,000) Asian Tour event.
Westwood, who finished third at this month’s US Masters, is five shots clear of Australian Kieran Pratt, who posted a sparkling 65 at the Royale Jakarta Golf Club.
Zaw Moe of Burma was on eight-under through 12 holes, three behind Westwood, before play was abandoned due to the threat of lightning.
Play was also suspended earlier in the day for two hours and 20 minutes for the same reason.
Moe will be among 74 players who will return early on Saturday morning to complete their second rounds.
Westwood, who played in the morning, struggled with the humidity but believes the extra rest will give him an edge over the chasing pack.
“You want to be leading tournaments and I obviously got the hang of playing on this golf course. More importantly, I was patient and I didn’t force things to happen.
“I’m glad I finished. I can relax this afternoon and prepare for the weekend,” said the Englishman.
Pratt three-putted for bogey on his opening hole but made a brave comeback with 10 birdies against two more bogeys for a total of 138.
It was a polished performance from the Australian, who shot an opening-round 73.
“I was frustrated yesterday. I felt like I was sort of playing OK but didn’t putt very well,” he said.
Another Australian, Rick Kulacz, was four shots adrift of Pratt after rounds of 69 and 73.
