Jeff Overton maintained a one-stroke clubhouse lead at the Turning Stone Championship today as weather wreaked havoc at the Atunyote Golf Club.
Heavy rain and hail resulted in two suspensions of play and the second round was eventually suspended due to darkness with 23 players still on the course.
Leading by one shot at the start of the day, Overton overcame a bogey on his first hole to card a three-under-par 69.
The American is at eight-under 136 through 36 holes, one stroke in front of Tag Ridings who signed for a four-under 68 on Friday.
Australian Jason Day is a further shot back on six under after firing a 69 which included a hole-in-on on the 179-yard sixth hole.
Fellow Australians Mark Hensby (69) and Robert Allenby (68) are tied for fourth with Charles Howell III (68) on five under.
Overton has yet to win on the PGA Tour with his best finish this year being a tie for ninth at the AT&T National.
After bogeying his opening hole, the 25-year-old rebounded with three birdies on the front nine at the fourth, eighth and ninth.
He had just one more birdie coming in, but it was enough to maintain the lead over Ridings, who carded six birdies and two bogeys on Friday.
Defending champion Steve Flesch, who is trying to salvage a season which sees him ranked 71st on the money list, is 11 shots off the lead following a 73.
