Duminy, the Delhi Daredevils skipper, has scored 220 runs at an average of 44 in his first seven games for the Indian franchise. He also captured seven wickets at an average of 11.28.
The 30-year old player was particularly devastating in the win against the Sunrisers Hyderabad, scoring 54 off 41 balls and then taking four for 17 with his off-spin.
Duminy has been a revelation with his match-winning innings at number three, instead of filling the customary number-six role.
“JP loves the responsibility of being captain and leading as well as fulfilling a senior role,” said Ontong.
“I am glad that Delhi has promoted him to the number-3 spot. He needs a bit more time to settle in. I hope South Africa will also use him higher up the order. He bats hopelessly too low (in T20-matches),” said Ontong.
“Many observers say JP is a good finisher. But people forget he is a good batsman, period. In T20-cricket, your best batsmen should bat for the majority of the overs.
“The Bangalore Royal Challengers have also moved AB de Villiers to number-three in the batting order. That is another good move. He should also bat higher up the order for South Africa,” said Ontong, who recently captained South Africa in a T20-International against the West Indies.
Duminy has been a revelation since he was moved by the coach, Gary Kirsten, to the number-three spot.
The stylish left-hander is no stranger to the top of the order.
He previously also opened the batting for the Nashua Cape Cobras in limited-overs competitions and can play the twin role of accelerator and finisher with aplomb.
