Reasoning: [structural reuse of KXPGAMAJORWIN-26-RHEN/KXPGAR1LEAD-THOC26-RHEN] [structural reuse of KXPGAMAJORWIN-26-PREE/KXPGAR1LEAD-THOC26-PREE] Winning a major doesn't require leading after Round 1 of the Open (could win a different major or come from behind), and leading Round 1 doesn't guarantee winning the tournament or any major.
