AKRON, Ohio, Aug 9 (Reuters) - Jordan Spieth gave himself ideal momentum heading into the PGA Championship at Whistling Straits as he signed off with his best score of the week at the WGC-Bridgestone Invitational on Sunday.
The Masters and U.S. Open champion fired a sparkling four-under-par 66 in the final round at Firestone Country Club to climb into the top 10 at the elite World Golf Championships event.
"Today was a good solid round," world number two Spieth told reporters after racking up six birdies and two bogeys on the challenging, heavily tree-lined layout.
