'All I know is I'm playing well now,' said McCord. 'It's a lot of fun.'
McCord, who is looking for his third win on the Senior Tour and first since 1999, had a flawless round of golf with nine birdies and no bogeys en route to an 18-hole career best.
The golf announcer birdied the second and third holes, both from outside 20 feet, before birdieing the par-5 7th. McCord went on to birdie five of the next seven holes to open a two-stroke advantage over his closest challenger.
'It was just fairways and greens today,' he said. 'I was driving long and making the par-fives easy.'
McCord closed out his round with a birdie on the par-5 18th to give him a perfect mark on the par-5s at the Dominion Country Club.
Bobby Wadkins finished two behind McCord at 7-under 65. The Long Island Classic winner was even through the first four holes before sinking a 25-footer on the par-3 5th for the first of three consecutive birdies.
'After I made the first birdie it got me going,' said Wadkins. 'After that I made a second and it was what I needed to do.'
He finished with a birdie on the closing hole to move under-par on all the par-5s.
Bruce Fleisher came in one stroke behind Wadkins at 6-under 66. Fleisher played a remarkable stretch with seven birdies over the span of nine holes, but bogeys on Nos. 6 and 16 disrupted a flawless round.
Defending champion Doug Tewell took the lead for the early part of the round. He posted a bogey on the par-3 5th but countered with an eagle on the ninth from 45 feet. He added birdies on Nos. 11 and 13 but managed only pars on the remaining five holes.
Tewell is joined by Mike Smith, Larry Nelson, and Bruce Lietzke at 5-under 67.
A group of six players closed out the opening round at 4-under 68 including current money-leader Allen Doyle. Doyle carded five birdies and one bogey to finish alongside Jim Thorpe, Lanny Wadkins, Bob Gilder, Bob Murphy, Terry Dill, Terry Mauney.
Bill Rogers made his Senior Tour debut Friday. The 1981 British Open winner managed a 4-over 76.
