After keeping his cool in regulation play to tie with Phil Rodgers, one shot ahead of Jack Nicklaus, Charles proved clinical on the greens in the last ever 36-hole play-off at The Open.
He one-putted 11 holes in the first round of the play-off to open up a healthy lead, before kicking on to beat Rodgers by eight strokes with a score of 140.
Charles had just 56 putts over the 36 extra holes, nine fewer than his vanquished rival.
