Hideki Matsuyama shot a 6-under 64 to finish the second round tied for second at the Wyndham Championship on Friday, two strokes behind the leader.

Matsuyama, starting the day in eighth, had no bogeys at the par-70 Sedgefield Country Club, carded six birdies, five on the back nine, for a second-round total of 10-under 130 to sit alongside Americans Kevin Na, Jim Furyk and Lucas Glover behind sole leader Kim Si-woo of South Korea.

Matusyama, who finished 15th here in 2013 but missed the cut the past two years, is anything but happy with his shots despite reaching the green in regulation 86 percent of the time and hitting the fairways 75 percent of the time, the seventh- and sixth-highest figures in the field, respectively.

"It was weird to see me climbing up the leaderboard when (my shots were) not on form," Matsuyama said. "I'm not hitting well at the practice ground either. They're not following the trajectory I'm looking for, and there were only one or two good shots today if I have to choose."

The 24-year-old, seen checking his swings throughout the round, narrowly missed several birdie putts on the front nine before finally succeeding on No. 5. He sank a 5-yard birdie putt on the 10th to kick-start his back-nine surge.

"I don't worry about the course, I don't dislike it," he said. "These little misses are ones I can live with, I'm reaching the green all right and that's leading to the score."

"I can't really hope for much with these kinds of shots and putts. But I'm in a good position and hope to enjoy playing."
