Confidence: high

Reasoning: If Koepka finishes top 10 in all 4 majors, he necessarily finishes top 10 at the Masters, which is within the top 20. The reverse does not hold: finishing top 20 at the Masters alone does not mean top 10 in all 4 majors.
Strategy: Buy NO on antecedent + YES on consequent
