For the third time in his PGA Tour career, Sepp Straka hoisted a trophy at tournament's end. Converting a four-stroke lead at the 54-hole mark into a victory at the 2025 American Express, Straka fended off a crowded chasing pack headlined by Justin Thomas.

Sepp Straka won The American Express by two shots over Justin Thomas. The 31-year-old Austrian finished his third career PGA Tour victory at 25-under 263 with a final-round 70.

I think that was the biggest challenge today was keeping aggressive on my targets,” Straka said after his two-under 70. “Nerves, just complete nerves. Stomach in a knot, the whole nine. So, yeah, just really excited about the way I handed the pressure today.
