New Proteas batting prodigy Jordan Hermann and his girlfriend Inge Krog.

Proteas new batting star Jordan Hermann may want to take his girlfriend, Inge Krog, all over the world with him as he navigates his international career.

Hermann struck 150 in his Proteas ODI debut in Windhoek on Wednesday, equalling Proteas teammate Matthew Breetzke's world-record score in South Africa's 99-run win over Namibia.

The stylish left-hander believes his good fortune was a result of Krog's presence in the stands.

"My girlfriend was also here. I believe she's a bit of a good luck charm," he said post-match.
