The round was delayed two hours, 25 minutes by inclement weather and eventually was suspended for the night by darkness. The round will resume Friday morning with the second round starting as scheduled at 7:00 a.m. (et). Due to heavy rain before the event, lift-clean-and-place rules were in effect for the round.
Tom Scherrer, defending champion Esteban Toledo and David Morland IV each carded rounds of 5-under-par 67 to share second place. Rick Price is alone in fifth at minus-four.
Rummells played the back nine first on Thursday. He dropped in his first birdie on No. 12 at Peek 'n Peak Resort's Upper Course. Rummells made the turn at minus-3 as he birdied the 16th and 18th.
The two-time winner on the Nationwide Tour made it two straight as he birdied the first to get within one of the lead. Rummells then drained an 8-foot eagle putt on the par-five second to jump into the lead at 6 under.
Rummells, however, stumbled to consecutive bogeys from the fourth to slip back to minus-4. He quickly regained those lost strokes though. Rummells birdied the par-three sixth and par-4 seventh to regain the top spot.
'Finally, it's the first time all year I've putted well,' Rummells admitted. 'From tee to green, I've been hitting the ball well, but my putting has been atrocious. This year, without a doubt, it's the worst I've ever putted.'
Due to this, Rummells recently switched to the 'saw' grip.
'I really didn't want to try it because it looks so ugly, but I was desperate,' Rummells stated. 'A friend of mine said try it and see what happens. You might be pleasantly surprised.'
Morland got off to a flying start with birdies on two and three. The two-time winner on the Nationwide Tour then holed his 7-iron tee shot at the 183- yard, par-3 fourth to jump to minus-4. That was the ninth ace in tournament history.
The 37-year-old then birdied Nos. 6 and 9 to make the turn at minus-6. Morland tripped to a bogey at the 15th. He recovered that stroke with a birdie on 17, but closed with a bogey at the last to end one back.
Toledo dropped in back-to-back birdies from the fifth. He then ran off three birdies in a four-hole stretch from the 14th to get to minus-5. He parred the last to cap a bogey-free round.
Scherrer got going with an eagle at the par-5 second. He came right back with a birdie on the fourth. After five straight pars, Scherrer birdied the ninth and 10th to get to 5 under. He parred his final eight holes to end there.
Jason Dufner, Tom Gillis and David Mathis share sixth place at 3-under-par 69. They were joined there by Charlie Wi, who is minus-3 through 14 holes.
Fourteen players including -- Joel Edwards, Kyle Thompson and Russ Cochran -- are tied for 10th at 2-under-par 70. Jin Park is also 2 under par through 16 holes of his opening round.
