Jonathan Byrd, a two-time winner on the PGA Tour, is alone in second place at 7-under-par 65. Kevin Na, Tom Pernice, Jr., Bo Van Pelt and Tom Byrum are knotted in third place at 6-under-par 66 at Annandale Golf Club.
'It is kind of amazing that we are even holding the golf tournament this week,' said Tway. 'It's pretty neat to see that they were able to persevere and have it.'
Tway began on the back nine Thursday and promptly birdied his first hole after he played a 9-iron to 20 feet. He parred 11, but hit a 7-iron to 2 feet to set up birdie at the 171-yard, par-3 12th.
He parred his next three holes, then hit a sand-wedge to 10 feet for a birdie at 16. Tway closed his opening nine in style as he reached the green with a 3-iron for his second shot at the par-5 18th. He two-putted from 12 feet to make the turn at 4-under 32.
Tway continued his strong play on the front side as he rolled in an 8-foot birdie putt at the first. After a par at the long, par-3 second, Tway caught fire.
He kicked in a 3-foot birdie putt at three, then ran home a 7-footer for birdie at four. Tway reached the par-5 fifth in two with an 8-iron, thanks to the hole playing downwind, and two-putted from 42 feet. He hit an awful eagle putt, but converted from 7 feet.
Tway hit a 9-iron to 10 feet and sank the birdie try at six for four birdies in a row.
Tway parred seven and eight, but made a mess of the par-4 ninth. His 9-iron approach missed the green left and his chip stopped 12 feet from the hole. Tway missed the par-saver, but still has the first-round lead to himself.
'I just played really well today,' said Tway, whose last win on tour came at the 2003 Canadian Open. 'I drove the ball well and hit my irons really well. I gave myself a lot of opportunities and a lot of them were really close.'
The Tway family has enjoyed a strong 2005 year, but it was more son Kevin and not dad. Kevin Tway won the U.S. Junior Amateur Championship this summer, but Bob Tway has only three top-10s this season.
'His win was huge. Bigger than any win I have ever had,' said Tway, who was later reminded about his PGA win. 'It was a great week for he, and I would love to win a golf tournament before the year is over.
'I haven't played very well all year and for some reason today I hit the ball really well - close to the hole and made a lot of birdies. It was nice to shoot a good round in the morning.'
Byrd, who tied for fifth place at the 84 Lumber Classic, mixed five birdies and an eagle on Thursday. He is hoping to continue a run of solid golf, as he has not missed a cut since late August.
Kirk Triplett, Joey Snyder III, Brian Henninger and Paul Gow are tied for seventh place at 5-under-par 67.
Triplett needs a strong finish this week, as this is the final full-field event of the year. Triplett is 131st on the money list and players in the top-125 at the end of this week retain their playing privileges for 2006.
