Scottie Scheffler's second round at the PGA Championship got off to a rough start, and he wasn't alone in his struggles. The world number one entered Friday at three-under par, sitting among the leaders at Aronimink, and was eager to build on his strong opening day. However, things quickly went south for the defending champion.

Scheffler set a personal worst record early in round two, missing his first six fairways—a feat he had never experienced before in his career. The streak finally ended on his ninth hole of the day, the 18th, where he found the fairway. By the turn, he had hit just one of seven fairways, a stark contrast to his near-perfect performance on Thursday.

On day one, Scheffler hit 10 of 10 fairways to start the round, the best such streak of his career in a major championship, according to Justin Ray. His driving accuracy plummeted from 92.86% (13 of 14 fairways) on Thursday to just 14.29% (1 of 7) on Friday, dropping him from a tie for first in the field to 78th in that category.

Scheffler finished day one at three-under par but quickly fell to one-under after shooting two-over on his first nine holes. While his wayward tee shots were a major factor, he still showed flashes of brilliance elsewhere on the course. The four-time major winner, defending his PGA Championship title, entered the turn with one birdie, five pars, and three bogeys.

Windy conditions made Aronimink even more challenging early on Friday, but Scheffler is known for embracing tough courses. Fortunately for those starting later in the day, the wind settled somewhat, which could help Scheffler find his rhythm on the back nine as he looks to climb back up the leaderboard.
