Marco Jansen fought tooth and nail (54 off 17 balls) but his efforts didn't bear fruit as Team India edged past South Africa in the T20I series by registering an 11-run victory in the third T20I at Centurion Park on Wednesday.

Earlier in the match, southpaw Tilak Varma scored a maiden Twenty20 International century with a brilliant 107 from 56 balls to help India get to an imposing 219 for six in their 20 overs.

Abhishek Sharma's fiery 50 also rubbed salt into Protean wounds as the game seemed out of South Africa's reach on most junctures of the match.

Spin to win

South Africa were always behind in their chase in the face of some excellent spin bowling from Axar Patel (1-29 in four overs) and the wiles of seamer Arshdeep Singh (3-37), but a late flurry of runs got them close.

They managed 208 for seven in reply and trail India 2-1 in the four-match series with the final game to be played in Johannesburg on Friday.

Varma and Sharma put on 107 from 50 balls for the second wicket to lay the platform for the visitors as South Africa lacked discipline with the ball, conceding 10 wides and three no balls in the innings.

Varma reached his century from 51 deliveries as he struck eight fours and seven sixes.

Ant attack

The South African reply was an over old when the players were forced from the field for almost 30 minutes by a swarm of flying ants.

When they returned, India's spinners squeezed the run-rate in the middle overs, though the home side were kept in the contest by Marco Jansen's career-best 54 from 17 balls and Heinrich Klaasen's 41 from 22 deliveries.
