Jazz Janewattananond found the going tougher at Augusta on Saturday, a disappointing 75 dropping the Thai ace back into a share of 44th spot on one-under par, 15 shots shy of runaway leader Dustin Johnson.

After returning to the course early to close out his second round with four pars, Jazz endured a rocky start to round three, moving from four-under to level par in the space of five holes.

The 24-year-old who is making his first appearance at Augusta steadied the ship somewhat with birdies at seven and 15, but left the course with a sour taste after letting a shot go at 18.

Despite the late slip, Jazz will surely be content with his efforts and will relish the prospect of teeing it up alongside PGA Championship winner Collin Morikawa and Charles Howell III on Sunday.
