Durban, April 19 -- Indian batter Jemimah Rodrigues admitted they were short of runs in the opening women's T20I but said the series presents a valuable opportunity for the batting unit, especially the all-rounders, to prepare for the upcoming T20 World Cup. India failed to build sustained momentum and finished with 157/7, a total that South Africa chased down comfortably to seal a six-wicket win in the series opener on Friday. "We were around 15-20 runs short. With the kind of start we got, I think Shafali Verma, the way she batted was great," Rodrigues told reporters. "Then two wickets falling in two overs, but then Harmanpreet Kaur and I getting that partnership back. I think when we had built that momentum and removed the difficult part of it, when time came to capitalise, we were not able to capitalise. "The conditions were a little bit tricky in the first innings. There was slight hold on the wicket. But, definitely, we were 15 runs short." Harmanpreet Kaur (47 not out off 33 balls) and Rodrigues (36; 29b) shared a 71-run stand (51b) in the middle overs to steady the innings. However, Rodrigues and Richa Ghosh (5) fell in quick succession, denying India a late flourish. "I know Harman and I could have gone deep. "Even Richa, little here and there, it was a six. So, sometimes when you come in, in such a position, you need to back yourself. It is like 1 out of those 10 times where it will go for a catch," Rodrigues said Richa's dismissal. "But I know 9 out of 10 times, she will hit it in the stands. So, I think we can definitely work on that because coming to the World Cup, we have batting till the end, a lot of all-rounders. "But also, the all-rounders coming later have not got so much match time and experience. So, I think playing here in South Africa is going to be really great for us as a preparation also for the World Cup and for our entire batting order too." India were also sloppy with the ball, conceding 14 wides as South Africa overhauled the target in 19.1 overs. Laura Wolvaardt (51 off 39) laid the foundation for the chase. Annerie Dercksen (44 not out off 34) then powered the hosts home with an authoritative finish with five balls to spare....
