Hideki Matsuyama shot a 3-over 73 to fall 12 strokes off the pace during the third round at the PGA Championship as American Brooks Koepka claimed the lead in the year's final major on Saturday.
Matsuyama, who carded a 1-under 69 in the rain-delayed second round, undid three birdies with four bogeys and a double bogey to fall into an eight-way tie for 63rd place at Bellerive Country Club.
The 26-year-old Japanese, who along with compatriot Yuta Ikeda carded a first-round 68 to open the day four strokes off the pace, bogeyed the first to set the tone for a challenging round.
