SUNRIVER, Ore. — Rod Perry shot an even-par 72 in rainy conditions Monday at Sunriver Resort to take the second-round lead in the PGA Professional National Championship.

Perry, the PGA head pro at Crane Lakes in Port Orange, Fla., had two birdies and two bogeys on the Crosswater Club course, the site of the final two rounds. The 39-year-old left-hander had an 8-under 135 total after opening with a 63 on the Meadows course.

"No lead is safe; that's for certain," said Perry, the 2012 PGA Professional Player of the Year. "Obviously, Crosswater is playing pretty tough. The crosswinds are there, and it's tough to get the ball close to the hole. It's tough to get the ball inside 8 to 10 feet. We have a lot of golf to play. Thirty-six holes on this golf course a lot can happen."

Mark Sheftic and Chip Sullivan, the 2007 winner at Sunriver, were a stroke back after shooting 4-under 67 on the Meadows course. The 38-year-old Sheftic is a PGA teaching pro at Merion in Ardmore, Pa., the site of the U.S. Open last week.

"Hectic is the right word," Sheftic said. "But, you have to say this, everyone that works at Merion and the members, it was a hectic week for us all. Being out here it's almost like a vacation. I don't know if I want to say it that way, because it's still a lot of stress. But it's fun to get out here and play some golf."

The 48-year-old Sullivan, the PGA director of golf at Hanging Rock in Salem, Va., holed out for eagle with a wedge approach on his opening hole — the par-5 10th.

"It is a good feeling to be back here," Sullivan said. "I feel like I have never left. I feel like I have the wave going. I didn't hit the ball as well as I'd like, but the putter saved me. I made a lot of two putts, and am really happy where I stand. I'm trying to relax and see if I can get the ball rolling tomorrow and make some more birdies."

Corey Prugh, tied with Perry for the first-round lead, was fourth at 6 under after a 74 at Crosswater. He's a PGA assistant professional at Manito in Spokane, Wash.

The top 20 finishers will earn spots in the PGA Championship in August at Oak Hill in Rochester, N.Y.
