Paul McGinley shot a second-round 68 which left him just inside the projected cut line at the Indonesia Open in Jakarta, which was interrupted by thunderstorms for a second day.
The two-time Ryder Cup winner closed on three-under-par 137 and tied with a large group for 61st place, having played 23 holes in the day.
Thailand's Thaworn Wiratchant holds the clubhouse lead on 14 under after his second round of 63, which included an eagle three at the 524-yard ninth, his last hole.
That was one ahead of Belgium's Nicolas Colsaerts, whose 62 was the equal best round of the day with Canada's Darren Griff.
The overnight joint-leader, Belfast's Michael Hoey, the 2001 British Amateur champion, recovered from a bogey five at the second to sink birdies at the fourth, sixth and ninth and move to 10 under and a share of third place with the back nine to play.
Among those to finish was Stephen Browne, who had six birdies in his second-round 66 to be seven under par and tied for 16th place.
Philip Walton added a one-under 69 to his opening 67 to lie on four under par and tied for 42nd, comfortably inside the cut.
McGinley was one of many to suffer on Thursday from the suspension of play and he returned yesterday morning to finish with five straight pars for a one-under round of 69.
He knew he had to dramatically improve on that and, starting at the 10th, he birdied the 11th.
But that was followed by a bogey four at the 245-yard next, and the Dubliner dropped further shots at the 15th and 16th.
The 178-yard 17th provided some welcome relief with a birdie, and further strokes were claimed back at the third, fourth and sixth.
But he faced an anxious wait this morning.
Colin Montgomerie's chances of winning, and therefore re-entering the world's top 50 and qualifying for next month's US Masters, were looking remote after he too was stuck on three under when lightning brought the players off the course at 5pm local time.
Montgomerie, three under overnight, played 10 of his first 11 holes in par, his only birdie coming at the short par-four seventh.
A bogey four at the 12th dropped him back again and he was in trouble at the next after his approach to the par four found an awkward, sloping lie adjacent to a greenside bunker.
He was prevented from making his difficult chip by the hooter to suspend play but will face a testing five holes when he returns.
Leader Wiratchant was understandably delighted with his finish. "It was a nice finish," he said. "I hit a good lobwedge that skipped into the hole.
"It was a long day. I had to come back to finish my first round this morning and had six holes to play. I got up at 5am and I'm feeling a bit tired now.
"But it is good to be at the top of the leaderboard and I'll do my best at the weekend."
Colsaerts does not have a European Tour card after finishing 120th on the Order of Merit last year, but equalled the lowest round of the week with nine birdies in a 62.
Hoey's overnight co-leader Arjun Atwal was actually pleased when play was suspended after struggling with his driver.
The Indian right-hander was two under through 13 holes of his second round and 10-under for the tournament, four off the lead.
"I wasn't playing well, my driver doesn't feel great," Atwal admitted.
"The grip is a bit thin and I've not been happy with my driving and that just falls on the rest of the game."
