Aditi Ashok will look at steady round to make the weekend action, while Diksha will need an under par second round to make the cut, which will fall at the end of two rounds.
Aditi shot even par 72 in the first round and was well inside the cut line, but Diksha carded 74 and was 2-over with the cut likely at 1-over on a sun-soaked day, it was tight at the top of the leaderboard as the players got to grips with the testing course at the final major of the year.
Aditi was Tied-33rd after the first round was completed, while Diksha was Tied-81. Their second rounds will begin and end very late in the evening.
While Aditi is seeking to better her best finish in a Major, which is T-22 in 2018 Women’s Open, Diksha is looking at making her first cut in her second attempt at the Women’s Open, which is the last of the five Majors for women.
Ally Ewing of the US fired an opening round of 68 (-4) to lead by one stroke at the end of the first day after overtaking five players, who shot 69 each.
When early action began on the second day, Ewing was 6-under through 13 holes and had moved to 10-under and six shots ahead of Lilia Vu of the US, who after 72 on the first day was 4-under for 16 holes and in second place.
It was three-time LPGA Tour winner Ewing who posted the round of the day making three bogeys, five birdies and an eagle to be on four-under-par.
One behind Ewing, five players were in a share of second place on three-under-par after round one at Walton Heath including 2020 Race to Costa del Sol champion Emily Kristine Pedersen.
The Danish star dropped a shot on the second hole but made an eagle on the 10th before adding birdies on 12 and 16 for her round of 69 (-3).
Pedersen sits in T2 alongside Korean duo Jeongeun Lee6 and Amy Yang, France’s Perrine Delacour and Thailand’s Jaravee Boonchant.
Yang had quite the scorecard on the first day with one double bogey, two bogeys, five birdies and an eagle for her round of 69 (-3).
One shot further back, there is a group of 12 players who are all in tie for seventh place on two-under-par including Spain’s Carlota Ciganda and Switzerland’s Morgane Metraux.
