Confidence: none

Reasoning: Finishing top 20 at the Masters requires making the cut, but does not logically require being the oldest golfer to make the cut. And being the oldest to make the cut does not guarantee a top-20 finish. No logical necessity in either direction.
Strategy: Buy NO on antecedent + YES on consequent
