The PGA Tour Policy Board - which early on in the commissionership of Bethesda's Deane Beman showed him he was no czar - has up and overruled him again, this time on his proposal to shorten the annual professional golf tour year.

Beman became the tour's commissioner in March, 1974, and in his major effort at clout, along about Memorial Day, 1975, the board vetoed his attempt to eliminate the Tournament of Champions at La Costa Country Club near San Diego from his domain."Why not cancel Christmas too" said Jerry McGee, typifying the horified reaction of the players - whose representatives on the policy board promptly put down Beman.

It's happened again. The pros can't see the green in a selective - the scarcer the gem the more valuable - schedule envisioned by Beman with the World Series of Golf as a grand, season's-end climax. They can't see it for smelling the greenbacks at Columbus, Ga.; San Antonio, Tex.; Pensacola, Fla., and the like in the autumn. On down to the Mickey Mouse conclusion in early November - that is, the finale opening today, the Walt Disney World National (two-man) Team Championship.

Said Beman, asked about the action at the board meeting in Lake Buena Vista, Fla., "Instead of a limited season, we are now looking at a potentially longer season."

But score one for Beman: he won board approval to end the tour fiscal year with the World Series, and make the fall events part of the following year's tour in terms of official earnings. Happy new in October; don't cancel Christmas; give us a break . . .

Bert Yancey, one of prof golf's top 50 all-time money winners with a $688,000 career, has ben taken to the state hospital in Columbia, S.C., for observation after his arrest on Hilton Head Island when a woman reported a prowler around her house at 1 a.m. Yancey, 39, the woman's next-door neighbor, was charged with peeping, indecent exposure, resisting arrest and destruction of Beaufort County property.

Handcuffed en route to county jail, he "went sort of berserk" and damaged the patrol car by kicking," said an officer.

Yancey, who joined the pro tour in 1964, left it this year to become a teaching pro at the Hilton Head Golf Club.
