Dave King and Gary Mankulish, tournament-tested veterans, will meet in a 36-hole showdown today at Indian Spring for the District of Columbia Golf Association championship, a title neither has won.

King, of Bethesda, came from behind a defeat defending champion Perky Cullinane of Columbia Country Club on the 20th hole. Mankulish, of Prince Georges, defeated Barry McCarty, Bell Haven, 3 and 2.

King and Mankulish have never met in match plays although they often have teamed in other tournaments and once won the Cumberland four-ball. King, 36, a statistician for the Public Health Service, won the Maryland State Amateur title in 1969 and 1971.

Mankulish, 24, has been runner-up in this tournament twice. He is now in the insurance business.

Cullinane missed a chance to win the first extra hole. He was on the $99[WORD ILLEGIBLE] in two and King, over the green made a poor chip 15feet from the hole. But Cullinane, who had a 50-foot putt, stroked it eight feet past the hole. He three-putted for a bogey and they went to the 20th hole, a 235-yard par-3.
