Michael Letzig posted a 7-under 65 in round one and is tied for third place at Midland Country Club. Brian Guetz is 7-under par through 10 holes.
There was a lightning delay that lasted slightly over two hours on Thursday. Play eventually resumed, but was called for darkness. The players will be back in position at 9:10 a.m. (ET) Friday morning to complete the round.
Toledo began on the back nine Thursday and flew out of the gate. He kicked in a 2-foot putt for birdie at 10, then sank a 10-footer for birdie at 11. Toledo polished off three straight birdies with a 5-footer at the par-5 12th.
At the par-4 14th, Toledo knocked his approach shot inside a foot. He tapped in for birdie, then two-putted from 15 feet for another at the 601-yard, par-5 15th.
Toledo, who won the 2005 Lake Erie Charity Classic at Peek 'n Peak Resort, missed the green at the par-4 17th. No matter, as the Mexican star chipped in for his sixth birdie and an opening nine of 30.
On the second nine, Toledo chipped in again, this time for an eagle at the par-5 second. He hit his second to 15 feet for another eagle chance at the fourth, but once again two-putted from that distance.
At 9-under par with five holes to play, Toledo struggled a bit with his driver. He hit a branch off the tee en route to a bogey at the seventh and any thoughts of a really low round were dashed.
'I thought about 11- or 12-under, but just missed a few too many fairways coming in,' admitted Toledo. 'When I missed the fairways, I was still able to hit good shots.'
Gessino-Kraft started poorly with a three-putt bogey at the third, but recovered with a birdie at the next hole. He closed his front nine with a 6-foot birdie putt at seven and a tap-in birdie at No. 9.
Gessino-Kraft continued his strong play around the turn. He knocked a wedge to 2 feet at 10 to set up birdie. He reached the par-5 12th with a 6-iron and holed the eagle putt to get to 5-under par.
At the 13th, Gessino-Kraft converted a 3-foot birdie attempt. He rolled in another short birdie putt at 14 and collected his third birdie in a row at 15 to join Toledo in the lead.
'I can't say I expected it,' acknowledged Gessino-Kraft, 88th on the Nationwide Tour money list. 'I haven't played that well here and I haven't played well lately.'
Garth Mulroy shot a 6-under 66 and is alone in fifth place.
Scott Sterling, Bob Burns, Jason Allred, Jeremy Anderson, Jon Mills, Patrick Sheehan, Keoke Cotner and Ron Whittaker are in the clubhouse tied for sixth at minus-5.
Chris Anderson, Michael Long, Kyle Thompson and Rich Morris are on the course at 5-under par.
