CAPE TOWN (Reuters) - South Africa's Faf du Plessis smashed a career-best 185 off 141 balls as the hosts beat Sri Lanka by 40 runs after surviving a fierce onslaught in a high-scoring fourth one-day international to take a 4-0 series lead on Tuesday.

After opting to bat, South Africa posted 367 for five in their 50 overs at Newlands but were then put under pressure by the tourists who made a magnificent start, only to wilt at the death to finish on 327 all out with nine balls remaining.
