The final round of the American Express is here, and Sepp Straka has a four-shot lead in search of his third PGA Tour victory.

It might not have mattered anyway, since Sepp Straka refused to buckle until it didn't matter. Straka, one of more than a dozen active PGA Tour players from the University of Georgia, followed up his third-round 64 with a 70 on Sunday at the Stadium Course and at 25-under-par 263 won The American Express by two shots over Justin Thomas (66).
