India captain Virat Kohli today said that the six-wicket victory in the first one-dayer against South Africa will give his side the momentum in the remainder of the six-match series. "First match of the series is important. We wanted to take the momentum of the (third) Test win into this and when we restricted South Africa to 270 on this sort of a pitch, we were happy," Kohli, who hit 112 of 119 balls for his first ODI hundred in South Africa, said after the match.
