Tiger Woods' impressive performance at last month's Open appear to have been an anomaly as he stumbled out of the gate Thursday at the 2018 PGA Championship.Slipping back to the form fans have become used to in recent years, Woods quickly fell behind his playing partners Justin Thomas and Rory McIlroy, after struggling right from the first tee.Woods' bogey-double bogey start was summed up perfectly by the Tiger Tracker twitter account, which tweeted: "Two-putt double bogey on the 11th hole. This is a nightmare. 3 over after 2 holes. #PGAChamp."Following Woods hole-by-hole, Tiger Tracker's dismay was clear to see over a number of frantic and critical tweets.Appearing increasingly agitated as the holes went on, the 42-year-old missed four of seven fairways during his rough start to the last major of the year, prompting Tiger Tracker to tweet in celebration when he found the fairway on the 12th."BREAKING NEWS: Tiger Woods found the fairway on the 12th hole," he posted, much to the amusement of his followers. A brief improvement after changing his shirt between the second and third holes of the day was short lived as he quickly dropped back to 3 over on the par 3, 16th hole.Woods' latest setback comes as a surprise following a positive performance at The Open, in which the four-time PGA Championship winner finished tied for sixth on five under.In a performance in which Woods carded his lowest major score since 2011, and even led the major going into the final day, he gave fans a glimpse of the Tiger Woods from time gone by.

However, the momentum gained at the Open has certainly dwindled away at the Bellerive Country Club in St. Louis.

No doubt the strong performances of his playing partners will only fuel his frustrations, with Justin Thomas, who missed only one fairway on his first nine, ended the day on one under.

Similarly, McIlroy bounced back from a bogey to open at 10 with birdies on 11 and 13. A bogey on the final hole ensured the Irishman made the turn at even par on the par-70 layout.

Woods himself also managed to finish his round at even par.
