Defending champion Tiger Woods will have to wait until Saturday to complete his round. Woods teed off in the afternoon at Warwick Hills and sent his second shot into a greenside bunker at the par-5 first.
The top player in the game had a difficult lie in the sand but hit out and watched as the ball rolled down the putting surface and into the hole for an eagle.
Woods had a birdie try that lipped out at the third and hit his approach inside 12 feet at the fourth before the weather delay of over four hours set in.
He returned to the course and parred the fourth, but Woods continued his charge with a birdie at the seventh. Woods then added a birdie at the 10th and reached 8-under with a birdie at the 13th.
Woods was at minus-8 through 15 holes when play was finally called for darkness. U.S. Open champion Jim Furyk was also on the course at 8-under through 14 holes. Woods and Furyk will return to the course with the rest of the players who were left in the dark at 9:00 AM (ET) on Saturday.
DiMarco was one of the lucky ones who were able to get their rounds in early.
'That's a shame,' DiMarco said laughing after his round when told that inclement weather was moving in. 'I would hate to see that happen.'
DiMarco stumbled early with a bogey at the fourth but responded with a birdie at the fifth after his second shot stopped within 10 feet of the cup. He kept things going with a birdie at the sixth and drained a 25-foot putt for a birdie at the eighth.
At the par-4 ninth, DiMarco struck a 9-iron to six feet and converted for a birdie to make the turn at 8-under.
DiMarco tallied a birdie at the 10th and dropped his tee ball inside six feet at the par-3 11th. He rolled in the birdie putt and continued his fine play with a birdie at the 13th.
The 34-year-old added a birdie at the 14th and played his third shot from off the green to four feet at the par-5 16th. DiMarco ran home the short birdie try for his ninth birdie of the day.
'You know, you just go out there and see what the course gives you,' said DiMarco, who has a victory on the PGA Tour in each of the last three seasons. 'I like to scoreboard watch, but I also know that I'm going to go out and try to make birdies and play aggressively.'
Sutherland torched the front side with five birdies to make the turn at 11-under par. He cooled off on the inward half, however, with two birdies and two bogeys for a round of 67.
'I feel like my game is hopefully kind of rounding back into shape,' said Sutherland, who is finished 36 holes at 11-under-par 133. 'It's been a while since I've played a lot of competitive golf.'
Gow was in the middle of playing the 18th hole when play was halted due to the torrential rains.
'I had a wedge into the last,' said Gow. 'But the tour has done the right thing. If it's stormy out there and we are in danger, they did the right thing.'
The Australian returned to the course after the delay and parred the hole to join Sutherland in a tie for second.
'The last four weeks have been real good,' said Gow, who posted a 67 in the second round. 'It's getting better and better. So this week is probably the best it's been in probably four years. It's all sort of gelling at the right time of the season.'
Andrew Magee fired a 64 to finish in the clubhouse at 9-under-par 135 alongside Garrett Willis and Neal Lancaster. Carl Paulson was at 9-under through 15 holes.
Hal Sutton and Danny Briggs also shot rounds of 64. They joined Kenny Perry and Paul Goydos at 8-under-par 136.
