Peter Uihlein of the United States made five birdies in gusty conditions and shot a 4-under 68 to take a one-stroke lead after the second round of the Shenzhen International on Friday.

Uihlein started his round on the 10th hole and was 1 under on the back nine, where the strong wind made play more difficult. He then added three birdies on the front nine to finish at 9-under 135 total.

Thailand's Kiradech Aphibarnrat matched Uihlein's five birdies, but added two bogeys to shoot a 69. He was one shot behind Uihlein.

Argentina's Emiliano Grillo matched the low round of the day with a 5-under 67 to move into a tie for third with Gregory Havret, Darren Fichardt and Matt Ford. They were three shots behind Uihlein at 6-under 138.
