Indian golfer Aditi Ashok was in contention for a historic Olympic medal after carding a flawless five-under 66 in the second round of the women’s competition here on Thursday.

Aditi, 23, rolled in five birdies, which included three in her last four holes, on yet another steamy day at Kasumigaseki Country Club to lie tied second on nine-under 133 with Danish duo, Nanna Koerstz Madsen (64) and Emily Kristine Pedersen (63).
