Sam Snead, who celebrated his 70th birthday by playing in the first round of Jack Nicklaus' Memorial tournament May 27, will play in the $350,000 Anheuser-Busch Classic starting Thursday at Kingsmill in Williamsburg. The purse has been increased by $50,000, to $350,000, and the event will be televised for the first time (NBC).

Snead won the first of his 84 professional titles in 1936.

Also entered are Bobby Clampett, toast of the British Open, defending champion John Mahaffey, Kingsmill touring pro Curtis Strange, Bill Rogers, Tom Weiskopf and Bob Gilder. Gilder made a double eagle en route to winning the Westchester Classic in late June. The following week he shot a Butler National course-record 64 in the first round of the Western Open, although finishing third. He was 29 under par for the two events and won $95,000.

Area pros entered at Kingsmill are Lee Elder, Woody FitzHugh and Fred Gibson.

Charley Boswell, playing in the Easter Seals tournament that concludes today at Prince Georges, has won the national blind golfers championship 17 times. His best score is 81. Boswell had planned a pro baseball career but was wounded in Germany in 1944 and blinded.

Jim Fitzgerald of Columbia and Peter Chapin of Longview each shot 69 yesterday to tie for the lead of the tournament after one round. The final round begins today at 9 a.m.

The Northern Virginia Amateur runs Friday through Sunday at Belle Haven. The tournament was to be played June 25-27, but heavy rains flooded the course. Except where water killed the grass on parts of the third fairway, the course is again in good shape and engineers are studying ways to prevent future flooding. Rob Black has turned pro and will not be able to defend his title . . .
