Brown made six birdies in a row on his front nine and had eight birdies in nine holes at one point. Brown shot an 8-under 64, rising to a tie for 41st. He began the day in 117th place after shooting an even-par 72 in his first round as a pro.

Blades Brown, 17, is making his pro debut at this week's 2025 American Express. On Friday, he's showing why he belongs on the game's biggest stage.

After reaching 11-under par with birdies on three of his first five holes Saturday and sitting well inside the cut line, Brown stumbled with three bogeys and a double bogey in his final 13 holes. The double bogey came when he put his tee shot in the water on the infamous par-3 17th with its island green.
