SLIPPERY ROCK — Competition will be stiff at the 21st annual Butler Eagle County Amateur golf tournament Sunday at Oakview Golf Club.

Tournament committee member Rob Voltz reported Monday that 124 golfers have registered for the 18-hole stroke play event. Plenty more may follow.

“We had 10 people sign up yesterday (Sunday) alone,” Voltz said. “We’re hoping to get another 30 or so this week.”

Sign-ups will be accepted as late as Thursday morning. Interested golfers may call Voltz at 724-822-4189.

Among those already registered are four former champions, including Voltz (2007), Doug Knox (2005) and defending champion Mike Marron. A Parker resident, Marron carded a 70 to win by two strokes last year at Lake Arthur.

Five-time Eagle Amateur champion Sean Knapp did not play last year, as the Eagle Amateur conflicted with the U.S. Amateur in Atlanta, Ga. Knapp is registered to play this Sunday.

He has won the tournament the last two times it was hosted by Oakview — in 2009 and 2012. Both fields had more than 150 golfers.

“Sean is one of the best amateurs out there and any tournament he’s in, the competition level shoots way up,” Marron said.

Cranberry Township resident Rick Stimmel, who has played in numerous WPGA events and has been a PGA pro, has verbally committed to play Sunday. Fellow Cranberry resident Brent Rodgers, the 2013 WPIAL individual champion with Central Catholic, has registered.

Rodgers reached the seventh of the 13-round Remax Long Drive World Championships in Nevada this year. Still only 19, he is a two-time West Penn Junior Golf Tournament champion.

He will be competing in the Eagle Amateur for the first time — and will be playing at Oakview for the first time in nearly four years.

“I’m looking forward to this,” he said. “This is the first year I’m not eligible to play a junior golf schedule, so I’m playing a tournament a week or every other week, as opposed to two or three events a week.

“My schedule’s been more relaxing. I’m not running around like crazy anymore. I’m hoping to get up there this week and get a practice round in.”

Rodgers, who averages 340 to 350 yards off the tee “while concentrating on accuracy” will play golf at Robert Morris University this fall.

On the women’s side, seven-time Butler Country Club champion Jane Wymer is back in the tournament after missing the 2014 event because of a family commitment. Wymer won the BCC title earlier this summer.

She tied Slippery Rock’s Jenna Rinker for the Eagle Amateur women’s title in 2013. Rinker bested Butler’s Marissa DeCola by six strokes to claim the women’s crown last year.

Rinker and DeCola are returning to the Eagle Amateur Sunday. Voltz said 10 to 12 women had registered as of Monday morning

“It will be fun. You want to go up against the best players in the county,” Wymer said. “The competition makes it exciting to play.

“If you win, you want to be able to say you’ve beaten the best local players.”

Rinker is a member of Oakview and has been “since I was a little girl.”

This will be her first Eagle Amateur at Oakview.

“Playing on my home course will be nice,” Rinker said. “Of course, I want to win it again, but I have no control over how well the other women do.

“I’m planning on enjoying myself, staying relaxed and play the best I can. Working full-time, I haven’t played a lot of golf this summer.”

She did play at Oakview Saturday and said the course is in great shape.

Voltz agreed.

“The course is playing firm and fast,” he said. “It’s really come back in nicely from where it was in early July.”

Marron said anything can happen in a single-day, 18-hole tournament.

“That’s the good and bad of it,” he said. “Anybody has a shot, but one bad hole can take you out of it.

“There’s not much margin for error.”
