Justin Rose heads into the final day of the Indonesian Masters three shots clear of the field at Royale Jakarta Golf Club, but with another 28 holes to play before victory is assured.
The bad weather persisted into the third day's play with most of the afternoon spent off the course under threat of a thunderstorm and earlier in the day the delayed conclusion to the second round had also impacted on Rose's position.
Cruising to 15-under through 29 holes, the Englishman was in total command of the tournament on Friday, but made a late bogey at the 15th as darkness descended and dropped another shot at 18 early on Saturday morning.
It meant he entered the third round just one shot clear of Kiradech Aphibarnrat (Thailand) and Scott Vincent (Zimbabwe) on 13-under 131, but he tripled that lead in the eight holes the three completed before play ended.
Rose made three par-breakers in that period and will resume early on Sunday at the par-5 ninth hole which he has already birdied twice this week.
For the two chasers, the latest disruption was timely. "I was not hitting it good today," said 25-year-old Vincent. "I need to go back, regroup and get some rest so I can make a charge tomorrow.
"I'm trying to be in the moment and win the tournament. I want to keep the momentum going. It's been really cool to play with Justin and Kiradech. I've learned so much already."
Aphibarnrat has mixed feelings heading into the final day.
"I'm very comfortable with my swing," he said. "But I'm worried about my back. It's been very stiff when I wake up. The suspension can be good or bad for me.
"I will try to do a lot of stretching in my room, try to keep my back safe, then go out and shoot a low one tomorrow."
Rose is 1.001 to complete victory with Aphibarnrat 1001.00 and Vincent 251.00.
