Bruce Lehnhard, who says his game is improving with age, shot a 2-under-par 70 yesterday to wipe out a three-shot deficit and win the Signet Open of Virginia with a 6-under 282.

"I'm a better golfer than I was 10 years ago, and I was better golfer then than I was 20 years ago," said Lehnhard, 47, who earned $7,560.

Lehnhard, the pro at Lake of the Woods, pulled even with Charlottesville pro Mike West, the third-round leader, with birdies on the 15th and 16th and West's bogey on the 17th. When West left his second shot short on the 18th and missed his par putt, Lehnhard two-putted from eight feet for par and the victory.

"I made two bad swings on 17 and 18, and they cost me," said West, 30, who won the National Assistant Pro championship last year.

Three-time state amateur champion Tom McKnight of Galax was third at 72 -- 285.

Gill FitzHugh of Arlington, last year's runner-up, shot 71 to finish in a three-way tie at 287.

Seniors: In Acme, Mich., Chi Chi Rodriguez started the day one stroke behind second-round leader Don January, but eagled the third and sixth holes -- both par-5s -- to win the Ameritech Open by seven strokes.

He shot a 66 to finish at 203, 13 under par on the 6,679-yard Bear course. His 15th victory on the Senior PGA Tour was worth $75,000.

Tied for second were George Archer, who shot 71, and Al Kelley, who carded a 70. January, who started the final round at 8 under, finished with a 76 -- 212.
