Fuzzy Zoeller was one shot back at the soggy Reserve Vineyards and Golf Club in the fifth and final major of the season on the Champions Tour.
Local favorite Peter Jacobsen is one of nine players two strokes back after an opening 69. Defending champion Tom Watson shot a 73 as golfers battled frequent squalls and slow play.
'It's not easy because it's so wet,' Canizares said. 'It's difficult to control.'
Galleries were sparse as downpours rolled through the area, the latest of several days of rain.
Jacobsen, who helped bring the Tradition to his home state last year after the event was held 14 years in Arizona, easily had the largest following.
Jacobsen teed off early, long before the late afternoon's bursts of sunshine. The forecast called for drier and warmer conditions over the weekend.
'At one point it was just pouring and I picked a guy out of the crowd and said, `You know, I HAVE to be here.'' Jacobsen said.
Jacobsen, who turned 50 in March, had hip surgery earlier this year, but returned to win the U.S. Senior Open, his first career major.
Jacobsen birdied the par-5 16th hole to move to under, but dropped a shot with a bogey at the par-4 17th
'I missed the fairway by about 2 yards to the right,' he said. The wet rough made it difficult to recover.
Fernandez was at 5 under going to the par-5 18th. He tried to reach the green in two, but his second shot sailed over the stands.
After a drop, his next shot settled about 20 feet from the hole, and he saved par.
Summerhays also had trouble at the 18th, hitting his tee shot into the tees and then grabbing his back. About the same time, dark clouds overhead opened up. He recovered and saved par
But Summerhays recovered and saved par. He said he simply had a bad swing on his tee shot - no injury.
'We had a great rainbow on that final hole, it was a beauty,' he said.
D.A. Weibring joined the large group tied for fifth after a 69. His strong showing came on the same day his 24-year-old son, Matt, was tied for second after the opening round of the PGA Tour's Buick Championship.
The 24-year-old Weibring is playing on a sponsor's exemption and is competing in just his third PGA Tour event. His father won the tournament in 1996 with his then-16-year-old son in the gallery.
Jacobsen won the Greater Hartford Open last year, but chose not to defend his title there so he could compete in his home state. Peter Jacobsen Productions, the golfer's sports management firm, runs the Tradition, sponsored by Oregon window and door maker JELD-WEN.
