Franklin Langham carded a 4-under-par 67 in round one and was joined in a tie for third place by D.J. Brigman and Johnson Wagner. The field battled cold, windy conditions during the opening round at Le Triomphe Golf & Country Club.
Weibring played the back nine first on Thursday and got off to a hot start. He chipped in for birdie on the par-3 11th and came right back with a short birdie putt on the 12th.
The Texan made it three straight as he birdied the par-4 13th from 25 feet out. After a pair of pars, Weibring tripped to his only bogey at the par-3 16th. He parred three straight around the turn.
Weibring, whose best tour finish came last year when he took fourth place at The Rex Hospital Open, moved back to 3 under with a 15-foot birdie putt on the second. He converted back-to-back birdies from the seventh to end at minus-5.
'It could have been really good. On both sides, I missed some opportunities,' said Weibring, who had wrist surgery in December. 'So it could have been better. It's hard to get it close on days like this. I made a couple of 25- footers which always helps on a day like this.'
Morland, a two-time winner on the Nationwide Tour, also played the back nine first in round one. He collected his first birdie at the par-five 12th. After parring the next four holes, Morland moved to minus-2 with a 15-foot birdie putt on the 17th.
Around the turn, Morland birdied the par-5 first after chipping to 4 feet. The 36-year-old moved into a share of the lead as he birdied the fifth and seventh, both par-fives. Morland parred his final two holes to share the overnight lead and close a bogey-free round.
'It was pretty tough out there,' Morland said. 'I was just trying to salvage pars and take advantage of the par-fives. The ball doesn't travel as far, so the holes play longer.'
Ryan Hietala opened his title defense with a 3-under-par 68. He is looking to become the first player in tour history to repeat as champion at an event.
Hietala was joined in a tie for seventh by Scott Gutschewski, Jason Buha, Craig Kanada, B.J. Staten, Peter Tomasulo and Scott Weatherly, as well as two of the season's first three winners - Tripp Isenhour (Panama Championship) and Jim Rutledge (New Zealand PGA Championship).
