Proteas women spinner Nonkululeko Mlaba climbed to second position in the ICC T20I Rankings after her fine performance in the Tri-Series between India and West Indies.
Last week, the Proteas defeated India by five wickets to win the Tri-Series final against India at Buffalo Park.
Mlaba took two wickets for 16 in the final in East London to finish with six wickets overall in the Tri-Series.
The 22-year-old left-arm spinner claimed the wicket of opener Smriti Mandhana for one in the second over and then claimed the wicket of Jemimah Rodrigues as India was restricted to 109/4.
Mlaba moved to a career-best 753 rating points, just 10 points behind England's Sophie Ecclestone.
