The plan is to bring the remaining half of the field back in position at 9:15 a.m. (et) Monday morning. The field will be cut to the low 64, then the match play portion will resume.
The first two rounds are stroke play and they are contested at the Canyon and Meadow Courses at Forest Highlands Golf Club. The match-play section will be staged at the Canyon Course.
Trip Kuehne is in the lead at six-under par as he is two-under through five holes at the Canyon Course.
Overnight co-leader Ryan Hybl is one-over through six holes of the Meadow Course and is part of a group tied for second place at minus-three.
Defending champion Kevin Marsh and Joshua Warthen are also three-under par for the championship playing the second round on the Canyon Course.
Jim Strickland is the clubhouse leader as he shot a three-under 68 on the Canyon Course on Sunday. He is through 36 holes at two-under-par 141.
'I was not thinking about medalist honors,' said Strickland. 'I was just thinking about qualifying. There's enough pressure to know that if you hit a ball offline and make a double bogey, all of a sudden you're on the cut line.'
David Bartman is two-under par for the championship still on the Meadow Course, while Joe Behl is at the same number on the Canyon Course. Alan Bratton is one-under for the championship and is on the Meadow Course, while Jeff Knox and Michael McCoy have yet to tee off on the Canyon Course.
