IRVING (Texas), May 16: American Ted Purdy fired a flawless final round five-under 65 to claim a one stroke win over Sean O’Hair and his first US PGA Tour title at the Byron Nelson Championship on Sunday. Twice a runner-up in PGA Tour events, Purdy took the final step into the winner’s circle with a polished last day at the TPC at Four Seasons Resort for a winning total of 15-under 265.

O’Hair, a 22-year-old Tour rookie whose only notoriety had been an overbearing father who made him turn professional before completing high school, began the day with a one shot lead.

He refused to wilt in the spotlight but settled for a career best second place after carding a final round two-under 68.

Vijay Singh used an ace on the 17th and birdie on the last for a final round five-under 65 to jump into a tie for third with Bob Tway and Doug Barron at 11-under 269, missing a chance to reclaim top spot in the world rankings from Tiger Woods.
