Thunderstorms ended play at the co-sanctioned Singapore Open on Friday after just six hours of golf were possible and with half the field yet to start their second rounds.
England’s Simon Dyson and Chapchai Nirat of Thailand were the joint leaders at six-under-par 65 mid-way through round two, while world number one Rory McIlroy was at one under par for the tournament.
Organisers did not make any announcement but last year’s event was slashed to 54 holes after similar disruption by storms.
McIlroy admitted he was struggling with a cold after completing his rain-interrupted first round five strokes off the pace in the morning.
The Northern Irishman, who can wrap up the European money title at the par-71 Sentosa Golf Club, finished his last 10 holes at one-under-par 70.
McIlroy is bidding to become just the second man to win the PGA and European Tour money titles in the same season, after Luke Donald achieved the feat last year.
