Sam Horsfield was disqualified from the Final Qualifier for The Open Championship played on Tuesday at West Lancashire Golf Club. He only played the first nine of the 36 holes scheduled for the event, and by then had a score of 7-over.The disqualification came about because Horsfield left the course after completing the front nine of the first round without notifying the officials. Although the player did not deny that his decision was related to his poor performance, he did explain that he was not in the best physical condition:"I felt completely dizzy and out of it all day," Horsfield posted on Instagram.The reason for his "dizziness" had to do with a bad night's sleep, as he himself explained:"I flew back home Sunday night and landed into [London airport] Heathrow at 4pm. By the time I got up to West Lancs, it was about late. Had a bit of dinner and fell asleep at 10:30/11," he said."At 1AM the fire alarm went off and we had to go stand outside for an hour or so. I eventually got back sleep around 5:30 for a 6am alarm, which I slept thru, but fortunately my caddy woke me up."Horsfield arrived in West Lancashire straight from playing the LIV Golf Dallas at Maridoe Golf Club, where he finished tied for 25th.The three-time DP World Tour winner has competed in three editions of the Open Championship with a made cut (tied for 67th in 2021).LIV Golf players qualified for The Open ChampionshipLucas Herbert was the only LIV golfer to qualify in West Lancashire, and he did so with mealist honors, finishing first with a score of 8-under.
