Thriston Lawrence started the day four shots behind the lead and produced a mixed round featuring eight birdies and five bogeys for a 69 to reach 13-under and win his second title this season at the BMW International Open. He is the second South African to win the trophy after Ernie Els.
"It means a lot. There's been a lot of hard work. I went to America for six weeks and made one cut - this game is not easy. It was a real boost today and I really gave it my all. I feel sorry for Joost, I know how tough this game is.
"I don't know why I'm so emotional but obviously it just shows that it means the world and to get my fourth victory in Germany is unbelievable.
"I seem to win a lot of events that Ernie has won. It's special, he's obviously the ultimate hero for me. I grew up in that era where he was on top of the world and it's very special to get my name alongside him."
54-hole leader Joost Luiten of the Netherlands closed with a 74 after making a single birdie and three bogeys to finish second at 12-under.
Japan's Rikuya Hoshino also signed for a 69 to close with a share of third place at 11-under alongside New Zealand's Daniel Hillier (71), Germany's Maximilian Kieffer (68)and Poland's Adrian Meronk (68).
