Debbie Massey, trying for her first LPGA victory since 1979, had her best round of the season at 7-under-par 65 yesterday and moved into a three-way tie two strokes behind leader Beth Daniel in the Phar-Mor Youngstown Classic in Vienna, Ohio.

Massey, Danielle Ammaccapane and Nancy Brown each had two-day totals of 136, leaving them two strokes behind Daniel's 10-under-par total. Daniel, who has won six LPGA titles since last August, has rounds of 65-69. Ammaccapane and Brown each shot 67 yesterday.

Tied at 138 were Patty Sheehan (70-68), Ayako Okamoto (70-68) and Dottie Mochrie (67-71).

Massey had eight birdies and one bogey on the 6,297-yard course at Squaw Creek Country Club, including a string of four birdies beginning at No. 13.

Signet Open:

In Richmond, Charlottesville pro Mike West shot a 3-under 69 and took a one-shot lead as the front runners faded.

West's round of four birdies and one bogey put him at 211 heading into today's final round in a bid for the top prize money of $7,560.

"After a while, I noticed nobody was doing anything," said West, who won the National Assistant Pro championship last year. "I thought if I could get something started, I could catch some guys. . . . I hit some really good shots on the back nine."

In second is Bruce Lehnhard, 47, a pro from Locust Grove, who carded a 67 over the 6,684-yard Willow Oaks Country Club Course.

Three-time state amateur champion Tom McKnight of Galax, who entered the round one shot off the lead, finished with a 73 -- 213. At one time during the third round, McKnight was 5 under for the tournament and three shots ahead of his nearest competitor.

Amateurs Allen Barber of Newport News, Mike Pratt of Richmond and J.P. Leigh of Chesapeake were the only other players under par, at 215. Amateur Gill FitzHugh of Arlington, last year's runner-up, had a 72 and was alone at 216.

Palmyra pro Jack Snyder, the second-round leader, faded to a 78 and 217.

Seniors:

Don January, using a modified putter grip, birdied four of the final five holes and took a one-shot lead over Chi Chi Rodriguez after two rounds of the Ameritech Open in Acme, Mich.

January's second-round 69 left him 8 under for the tournament at 136 on the 6,679-yard Bear course at Grand Traverse Resort.

January, 60, who hasn't won since 1987, could become the second-oldest winner on the senior tour. Mike Fetchick was 63 when he won the Hilton Head Seniors International in 1985.
