Punam Raut and Harmanpreet Kaur's batting efforts went in vain as the Indian women's team suffered a seven-wicket defeat against South Africa in the fourth ODI to concede the five-match series here on Sunday.
Asked to bat, Raut continued her rich vein of form with an unbeaten 104 while Harmanpreet smashed a blazing half-century to power India to a 266 for four in 50 overs.
In reply, opener Lizelle Lee (69), skipper Laura Wolvaardt (53), Mignon du Preez (61) and Lara Goodall (59 not out) smashed half-centuries to guide South Africa home.
The tourists scored 269 for three in 48.4 overs to take an unassailable 3-1 lead in the five-match.
India missed the services of veteran seamer Jhulan Goswami as other bowlers leaked runs everywhere. Mansi Joshi (1/43), Rajeshwari Gayakwad (1/39), Harmanpreet Kaur (1/38) took one wicket apiece.
The two sides will play the fifth and final ODI on Wednesday.
