Shaaban Hussein and Park Hyun-bin claimed the clubhouse lead at the Indonesian Masters as Lee Westwood's charge came to a halt when the second round was suspended due to lightning on Friday.
The world No 2 was alongside the leaders on nine under par and will have to return at 6.30am local time on Saturday to finish his last two holes at the Royale Jakarta Golf Club.
Shaaban and Park fired rounds of 67 and 68 respectively to lead by one from Thailand's Thitiphun Chuayprakong (68).
Pariya Junhasavasdikul, who shot the best round of the week so far with a superb 65, is another stroke back on seven under in the clubhouse alongside three other players.
A total of 47 players have yet to complete their second rounds. Thailand's Thongchai Jaidee was eight under with two to play.
Westwood, who reverted to a conventional putter on Friday, birdied his opening four holes before making the turn in 32.
He added a birdie and bogey on holes 12 and 13 respectively and birdied the 16th just before play was suspended.
"Obviously I'm disappointed because I had two more holes to play. I'm still in contention and have to see how things go in the next two days," Westwood said.
In China, Jamie Donaldson fired 11 birdies for a second-round score of 61 at the China Open, soaring to the top of the leader board.
Donaldson is one stroke ahead of seven players tied at 12 under at the Luxehills International Country Club in Chengdu, the capital of China's Sichuan province.
The Welshman's scintillating performance yesterday lifted him 57 places up the field, having shot a 2 under 70 in the first round.
Sergio Garcia of Spain was two shots back - alongside four others - after a round of 67.
