Seve Ballesteros' membership in the PGA Tour has been revoked and the Spanish golfer will not be allowed to play in tour cosponsored tournaments in the United States next year, Commissioner Deane Beman announced.

Ballesteros, however, will remain eligible for the Masters, the U.S. Open and the PGA. Those Grand Slam tournaments have their own eligibility rules. He also will be allowed to play in the USF&G Classic in New Orleans March 20-23, in which he is the defending champion.

The ruling, made by the tour's policy board at a meeting in New York Tuesday, came as a result of Ballesteros' failure to play in a minimum of 15 tour events in 1985, as required to retain membership . . .

Chris Peddicord of Winter's Run and Norm Vacovsky of Sparrows Point had the best round of the day, shooting five-under-par 67, and defeated Pete Van Pelt and Trevor Patmore of Woodlawn, 2 up, in the second round of the Middle Atlantic PGA's Two-Man Match Play Championship at Chantilly North.

John Dodson of Twin Shields and Mike Garner of Chesapeake Hills won the longest match of the round against Scott Singhass of Winchester and Joe Gullibeau of Piney Branch when Dodson chipped into the cup from 20 yards out for a birdie that won the third extra hole.
