Butler golfer Jon Pratkanis, bidding to become the first amateur to win the Pennsylvania Open since 1990, got off to a rough start in Wednesday's final round at Nemacolin Woodlands, Mystic Rock.

And Kyle Davis took full advantage of it.

The 20-year-old Davis of Kennett Square, an incoming sophomore at the University of Central Florida, carded a 69 Wednesday to beat out defending champion Sean Farren of Oakmont by four strokes for the title.

Pratkanis, 20, took a one-stroke lead into the final round of the 72-hole event, but began play Wednesday with a bogey, double bogey and bogey to fall out of contention. He wound up tied for third with fellow Butler resident Rob McClellan, five strokes off the pace.

McClellan was one of five golfers to have the lead at some point Wednesday and was 3-under-par with nine holes to play. He bogeyed No.'s 10 and 11, however, before parring out.

"I was tied with the eventual champion (Davis) with nine holes left,"McClellan said. "I told my brother, who was caddying for me, that two or three more birdies might do it.

"Then I three-putted on 10 and 11. I blew easy shots both times. That really hurt."

Formerly a pro at Olde Stonewall Golf Club in Ellwood City, McClellan recently accepted the position of first assistant pro at Butler Country Club.

Before tying for third in the Pennsylvania Open, McClellan's previous-best finish in a tournament this year was fourth at the Falling Rock Classic, also held at Nemacolin Woodlands.

The overall purse for the Pennsylvania Open was $50,000, with $10,000 going to the winner.

"I knew (Davis) was an amateur, so I was thinking about being the top-finishing pro,"McClellan said. "When you're playing for this kind of purse, nerves do become a factor. And nerves affect putting more than anything."

Davis finished at 6-under 210 for the tournament, putting together three consecutive rounds of below-par golf. He was the only golfer in the 132-player field to do so.

Farren matched Davis' round of 69 Wednesday, but shot a 4-over 76 Tuesday. Farren was bidding to become the first back-to-back winner of the Pennsylvania Open since John Weitzel of Hershey Golf Club did so in 1955-56.

Davis had a two-stroke lead on Farren, who was already in the clubhouse, with three holes remaining. He birdied the par-5 No. 16 hole by sinking a 30-foot putt, then birdied the par-three No. 17 hole to wrap up the title.

Davis needed only 27 putts during his round Wednesday.

Pratkanis shot a 76 in the final round with McClellan shooting 73. The Butler pair finished the tournament at 1-under, joining Davis and Farren as the only golfers to finish under par after all 72 holes.

Pratkanis could not be reached for comment Wednesday night.
