Hideki Matsuyama shot Friday's low round, a bogey-free 7-under 65, to climb into second place at the midway point of the Memorial Tournament.
The Japanese star, who began the day in a tie for 33rd, moved to a 7-under 137 total, one stroke behind Justin Suh of the United States at Muirfield Village Golf Club in Dublin, Ohio. Suh carded a 66 in the second round.
Matsuyama, teeing off on the 10th hole, picked up four birdies before the turn.
The 2021 Masters champion and eight-time winner on the PGA Tour then made three more between Nos. 5 and 8.
Asked to pick the best part of his day, Matsuyama responded, "My putting."
"To make those putts at 7 and 8 were huge," he said, according to the tour's official website.
He sank birdie putts of 25 feet at the par-5 seventh hole and 33 feet at the par-3 eighth.
Matsuyama, also the 2014 Memorial Tournament winner, is looking for his first victory since January 2022 at the Sony Open in Hawaii.
Americans David Lipsky and Patrick Cantlay are tied for third at 6 under for the tournament after rounds of 69 and 67, respectively.
