Phil and Bryson DeChambeau's best round is 55 (−15) at The Greenbrier in S01E10 — 6 shots shy of breaking 50 across 1 appearance. Best finish: #17 among duo rounds.
Phil Mickelson took on more of the workload than almost any guest — just over half the team's shots at The Greenbrier, some 2,720 yards of them. But Break 50 is an eagle hunt, and with only one all day, 13 birdies couldn't keep pace: the 55 (−15) stands as a reminder that even six-time major champions find this format unforgiving.
