The Indian women's team followed the script when they beat South Africa women by 54 runs in the fifth and final T20 international.
Harmanpreet Kaur-led side displayed an all-round performance as they outclassed the Dane van Niekerk-led team, bowling them out for 112 to lift the T20 series trophy by a margin of 3-1 in the five-match series.
“The team still requires a lot of hard work in a lot of areas when it comes to the T20 format. We have been very good in the one-day format, but the way the girls responded to this format in South Africa, I think there is a lot of scope that we can be a surprise element in the World T20,” Raj, 35, told ESPN Cricinfo.
“People back home were keen to watch on television, they wanted to know what the Indian women's team was doing in South Africa.
“It is just unfortunate the one-dayers weren't televised but I am happy the T20s were televised and we gave a very good result,” the veteran batswoman added.
Around Raj, there is a younger crop of promising young cricketers to ease the burden from her shoulders.
The likes of Smriti Mandhana, Harmanpreet Kaur and Veda Krishnamurthy provide middle-order muscle, and in 17-year-old Jemimah Rodrigues, who shared a 98-run stand with Raj in the series clincher, a star is being nurtured.
“Yes, that has helped my batting, knowing that the team is not completely dependent on me,” she said. “I can at times take that initiative to try out a few strokes in the middle, without getting bothered if I get out. I am very happy that we have more than one or two match-winners in the squad.”
Not a fan of the T20 format, Raj said she is confident of becoming a good player in the shortest format of the game by tuning herself to that mode.
“Honestly, I am not someone who is very fond of the T20 format. But since I am preparing for the T20 World Cup, it was important for me to start scoring runs in this format to gain that momentum.
"I am very happy that this series has given me that confidence that I can be a T20 player.
“It is a conscious effort to turn my game so that I can get used to the T20 format because as an opener it is important that I have all-round shots and also see that aerial route, because the first six overs are crucial.”
India's next international assignment is against Australia, with the first of three ICC Women's Championship matches beginning on March12.
It is a busy calendar for India as they will also host Australia and England in a T20I tri-series this month, followed by three ODIs against England at home.
