Despite winning the Challenge Cup for a fifth time in 1963, Wakefield had still not been able to secure the league championship title. The Holy Grail would be achieved in the 1966–67 season when the experienced Harold Poynton led a powerful side, which included Neil Fox, Don Fox, Gary Cooper and Ray Owen, to victory over St. Helens in a replay of the championship final. They repeated the title feat the following year against Hull Kingston Rovers but were again denied the double when Leeds defeated them in the 1968 'water splash' final at Wembley, a match played during a downpour that saturated the pitch. The game produced the most dramatic of finishes, when Man-of-the-Match, Don Fox had an under-the-posts conversion to win it for Wakefield, but "topped it" on the saturated turf and missed, to leave Leeds 11–10 winners.
