I think you may be getting two guys mixed up. Bland did have a great throwing arm, but he fielded in the covers and was possibly the greatest cover fielder of all time. My understanding is that he often used to entertain crowds during breaks and before the day's play by throwing a ball at a single stump from 25 yards and hitting it most times.

He was primarily a fielder, but whilst being Jonty-esque in the field, he was a better bat than Jonty ever was. I don't think he ever bowled though - or if he did, he couldn't have bowled much.

EDIT: Just looked him up on cricinfo, and he was actually Rhodesian (Zimbabwean). I wonder if there's some mileage in listing out all the Zimbabweans who ever played for South Africa and then doing a Zimbabwe XI based on those of Zimbabwean heritage?
