South Africa were cruising in their run chase with the in-form Laura Wolvaardt (80 off 79) and Lara Goodall (49 off 69) sharing 125 runs for the second wicket.

India rely heavily on veteran pacer Jhulan Goswami for early breakthroughs and her absence due to a side strain made the task easier for the South Africans.

Harmanpreet Kaur, who made 48 with the bat, got rid of opener Lizelle Lee (6) with a brilliant direct hit before Wolvaardt and Goodall got together and took the game away from the opposition. ?

Wolvaardt continued her sensational run of form with her fifth fifty-plus score in seven innings. It took a double strike from Harmanpreet to bring India back in the game as she found the stumps of Wolvaardt and trapped Sune Luus (22) with her probing off-spin.

The Indian fielding once again was sloppy and late evening dew made the job tougher for them. However, individual brilliance of Harmanpreet helped India take the game deep with South Africa needing 45 off the last 30 balls.

Shafali (53 off 46) and Smriti (71 off 84) shared a 91-run stand off 90 balls for the opening wicket to provide the start India were looking for.?

Shafali collected three boundaries off Shabnim's second over including an audacious walk across the off-stump to whip the South African bowler over short-fine leg.?

The 18-year-old completed her first fifty of the competition with a boundary over mid-on off pacer Masabata Klaas. ? ? ? ?

With the way the openers were going about their business, India looked on course for 300 for the second time in the tournament. However, they lost Shafali against the run of play before number three batter Yastika Bhatia got out in a bizarre fashion.

There was a miscommunication over a quick single on the leg side between Shafali and Smirti while Yastika played a sweep shot on to her stumps off spinner Chloe Tryon, leaving India at 96 for two from 91 for no loss.

Mithali and Smriti then got together to regain the lost momentum.

With Mithali going strong and Harmanpreet joining her in the middle, India found their rhythm back to reach 223 for three in 40 overs.

However, only 51 runs were scored off the last 60 balls for the loss of four wickets as India failed to get the final flourish.?
