Recalled J.P. Duminy scored a maiden one-day century as South Africa answered the call of coach Mickey Arthur with a 212-run victory over Zimbabwe at SuperSport Park Tuesday. Arthur demanded greater all-round ruthlessness after his team took much longer than expected to complete a 45-run victory Sunday in the first encounter. South Africa which was put into bat, ran riot to compile 331-5 off 50 overs before bowling Zimbabwe out for 119 in 34.3 overs for a 2-0 series win. Duminy, a 25-year-old left-hand batsman from Cape Town came in at No. 4 and tormented the visiting attack to finish unbeaten on 111 after facing 87 balls in 126 minutes.

In their final warm-up before the first of two Twenty20 internationals against South Africa in Johannesburg Friday, the tourists were bowled out for 89 by South Africa's second stringers. South Africa A also found batting difficult in a match dominated by spin bowlers but won with 15 balls to spare. The defeat followed easy wins for the tourists in 50-over matches against franchise teams in their first two fixtures. England failed to see out it 20 overs after being sent in to bat. It lost its last seven wickets for 18 runs in 32 balls as its innings lasted for only 17.3 overs. England were again without injured fast bowlers Stuart Broad and Graham Onions.
