Tiger Woods carded the third-worst round in a major of his career on Saturday after producing a miserable 79 at the US PGA Championship.

Woods had rebounded from a disappointing opening round of 74 to make the cut with Friday score of 69, which even he admitted "wasn't pretty".

However, things were far less pretty in his third round, especially on the sixth hole as he suffered a triple bogey.

Up until that point, the 46-year-old had not been doing too badly, making par on four of the first five holes (one bogey), but that setback on six led to a slide.

After another bogey at seven in tough conditions, Woods made par on eight before bogeying five holes in a row to sit on 10 over for the round after 13 holes.

The 15-time major champion was able to save some face after that, making par on 14 before his first and only birdie of the day at 15.

Three pars to finish saved his blushes as he just avoided carding 80, which he has only ever done twice at majors - scoring 81 in round three of the 2002 Open Championship, and 80 in the first round of the 2015 US Open.

He goes into Sunday on 12 over par, tied for 76th.
