Australia's Whitney Hillier carded a second-round 71 to claim a slender lead at the halfway stage of the Women's Indian Open.
Hillier birdied the last two holes at DLF Golf and Country Club to finish six under par and a shot ahead of Norway's Marianne Skarpnord, with England's Meghan MacLaren and Sweden's Linda Wessberg a shot further back.
"It was a little bit up and down in the middle there but I got it back really well, so I'm quite proud of that," said 28-year-old Hillier from Perth, who said she loves playing in the heat in India.
"I was two-over after 10 and then I got it back to finish one-under for the day. I hit it close on 17 and 18, where I used the slope quite well.
"It's funny, I'm from Joondalup Golf Club (WA), which is actually quite similar, shots wise.
"I just realised that this course has the 'Lake' and 'Quarry' nines, which is exactly the same as at Joondalup. I'm not kidding, it's so surreal."
MacLaren began the day tied for the lead with Hillier but could only add a 73 to her opening 67.
England's Charlotte Thompson fired the low round of the day with a 67 to lie three shots off the pace alongside Wales's Lydia Hall and Austria's Christine Wolf on three under.
Catriona Matthew is five shots off the lead after a 73, while shot of the day belonged to her fellow Scot Kelsey MacDonald, who made a hole-in-one on the 16th in her 72 to finish four over par.
