Matt Dobyns had a hole-in-one and shot a 3-under 69 on Tuesday to take a six-stroke lead into the final round of the PGA Professional National Championship.

The 34-year-old Dobyns, the PGA head professional at Fresh Meadow Country Club in Lake Success, N.Y., had an 11-under 205 total. He aced the 195-yard 14th hole and closed with an eagle on the par-5 18th on the Bayonet course.

The former University of Texas player opened with a 68 at Black Horse on Sunday, and took a three-stroke lead Monday with a 68 at Bayonet.

First-round leader Mike Small, the University of Illinois coach who won the event in 2005, '09 and '10, was second after a 72. Kelly Mitchum, a PGA assistant professional at Pinehurst (N.C.) Resort, was another stroke back at 4 under after a 72.

The top 20 will earn spots in the PGA Championship in August at Kiawah Island.
