Heavy rains drenched En-Joie for a large portion of the day. Thunderstorms passed through the area causing a weather delay of nearly four hours. The second round will resume at 7:30 AM ET Saturday.
Gow got off to an impressive start to take the clubhouse lead. He began with a chip-in birdie at the par-4 first and reached the green in two to set up an eagle at the par-5 third. Gow drained the 18-footer to quickly reach 8-under.
He birdied the fourth before his only mistake of the day at the following hole. Gow scrambled to reach the green at the par-5 and had a four-foot putt to save bogey but he failed to convert.
Gow countered with a two-putt birdie at the eighth and picked up another birdie at the 11th. At the par-5 12th, Gow reached the green in two and narrowly missed an eagle when his putt lipped out. He tapped in for birdie and added a birdie at the 17th to finish atop the leaderboard.
'Today was a bit like yesterday. I got off to a good start,' said Gow, who has had a disappointing season thus far with 14 missed cuts in 20 starts. 'I'm playing better coming in here than I did last year. The last time I putted well was here last year. It's kind of eerie it is happening again.'
Paul Claxton was also able to complete his round Friday. He took second in the clubhouse at 10-under-par 134 after a round of 69.
First-round co-leader Joe Ogilvie carded a 2-under 70 to finish at 9-under-par 135 alongside Bo Van Pelt. David Peoples was one shot further back at 8-under-par 136.
Shaun Micheel, who held a share of the lead after the opening round, had to wait over four hours to tee off Friday. The delay started at 12:47 PM ET and players did not return to the course until 5:00 PM.
Micheel was not affected by the rain as he started his round on a blistering pace with a stretch of four consecutive birdies starting at the second. He moved to 12-under with a birdie at the ninth but fell back into a tie with Gow after a bogey at the 11th. Micheel was through 15 holes when play was suspended.
Defending champion Jeff Sluman, who outlasted Gow in a playoff last year for the title, recovered from an opening round 72. The six-time PGA Tour winner was at 4-under through 14 holes.
