Little-known Andrew Landry was clinging to a one-shot lead with one hole to go when play was suspended for the day, with only nine of the 156-strong field completing their rounds. Defending champion Jordan Spieth and world number three Rory McIlroy will be hoping to turn things around when they return to finish their first rounds on Friday. If Landry was an unlikely name atop the leaderboard at three-under par through 17 holes, 19-year-old American amateur Scottie Scheffler was an equally surprising clubhouse leader after a one-under 69.
