World No.1 Jason Day has started his US Open tilt extremely poorly, falling 10 shots off the pace after the opening round at Oakmont Country Club.
Day shot an opening round six-over 76, his equal worst US Open round and worst major round since a 77 in the 2013 British Open.
The pre-tournament favourite is now in a battle just to make the cut, let alone win his second major.
No player has won a major with an opening round 76 or higher since Jack Fleck in the 1955 US Open.
Clearly out of sorts, Day has just a short break before being sent out for his second round as the field tries to catch up from multiple rain delays on Thursday.
Earlier little known American Andrew Landry bested golfing titans Gary Player and Ben Hogan in posting the lowest opening round at Oakmont in US Open history.
Landry, the world no. 624 from Texas who is playing in his first major championship, came back after Thursday’s lengthy rain delays and buried a birdie on his final hole to post a four-under-66.
The mark eclipsed Hogan and Player who previously shared the record at 67 on the notoriously tough course.
England’s Lee Westwood and American Dustin Johnson have started their quests for a breakout major championship well, sitting tied second after rounds of 67.
Scott Piercy, Shane Lowry and Sergio Garcia are just two back at 68.
Adam Scott, Marc Leishman, Cameron Smith and Geoff Ogilvy lead the Australian charge after the quartet all shot 71, five shots back.
Aron Price joins Day at six over and Steven Bowditch is in real trouble after an 84.
Defending champion and world No. 2 Jordan Spieth shot 72 while world No.3 Rory McIlroy struggled to a 77.
