Elsewhere, Kiwi Daniel Hillier has made a strong start in the opening round of the International Open in Munich on the DP World Tour.
Hillier was four-under through 15 holes when play was suspended due to lightning. Hillier had a hot start to his round, sitting five-under through six holes following three birdies and an eagle before a double bogey halted his charge. He bounced back with two more birdies and a bogey and will finish his opening round tomorrow.
Edoardo Molinari of Italy, France’s Adrien Saddier and Rikuya Hoshino of Japan lead the way at six-under.
