2023 AT&T Byron Nelson leaderboard, scores: Scottie Scheffler near lead after hot start in Round 1

Scheffler is chasing, but Seung Yul Noh won't be comfortable even with a healthy lead

A final tuneup is underway ahead of the 2023 PGA Championship, and -- surprise, surprise -- Scottie Scheffler is in contention.

The six-time PGA Tour winner looked like he was going to scare the all-time PGA Tour scoring record in a single round (58, Jim Furyk) through the first part of Thursday. He cooled off late, but he's still within four of the lead going into Friday's second round with just three players ahead of him.

Seung Yul Noh leads after 18 holes, and speaking of scaring scoring records, he did so (with some defunct equipment no less!) on Thursday. Noh shot a wild 11-under 60 and leads Adam Scott and Marty Dou by three each after Round 1.
