India's S Chikkarangappa grabbed a share of the sixth position after carding 71 and 66 on a day when he had to play 30 holes at the weather-hit SMBC Singapore Open on Friday.
Chikka had seven birdies against two bogeys in his five-under 66 and he is now five-under for the tournament.

The third round is not scheduled to start before 12pm.
Among other Indians in fray, Arjun Atwal (67-73) is Tied-36th. Shiv Kapur, even par on first day, was one-over through seven in second, while Rahil Gangjee was two-over for 30 holes after carding 76 on first day and being three-under through 12 holes in second.
