Japan's Hiroshi Iwata matched a major championship record on Friday with a nine-under par 63 in the second round of the 97th PGA Championship.
Iwata's round at Whistling Straits marked the 27th time a player has shot 63 in a major, with two players -- Greg Norman and Vijay Singh -- doing it twice.
The most recent prior 63 at a major championship was Jason Dufner en route to the PGA Championship title in 2013 -- the 13th time the score was achieved in the PGA Championship.
