JOHANNESBURG, Jan 7 (Reuters) - Jaco van Zyl picked up where he left off before the festive break by shooting a seven-under-par 65 to grab a one-stroke lead after the South African Open first round on Thursday.
In second place on 66 in the European Tour event at Glendower Golf Club was fellow South African Shaun Norris, one ahead of compatriots Keith Horne and Jbe Kruger.
A threat of lightning meant play was suspended late in the day with 33 players still out on the course. They will return to complete their rounds on Friday morning.
