The Frenchwoman struggled on the greens in Friday’s second round, failing to make the most of her birdie chances in a one-under round of 72 after opening with a fantastic 64.
She only managed birdies at the fifth and ninth, after dropping a shot at the fourth, nothing like the nine-birdie effort that started the tournament off on Thursday.
Nocera, 12 times a winner on the European Tour, still managed to hold off the challenge of Indian rookie Vaishvani Sinha and there are three more strokes back to third-placed Thidapa Suwannapura, the defending champion from Thailand.
“I played well but the putts didn???t drop. Today 15 greens and 33 putts. Yesterday I had 26 putts,” Nocera said.
“I think the pins were tough today – beside major slopes – and it was tricky.”
Sinha was unhappy with her round which included five birdies and three dropped shots.
“Yesterday I hit 12 greens and today I hit 10 greens,” said Sinha. “My hitting was a lot worse today and it was quite frustrating because I didn???t miss greens just on the edge, I was missing way left and they were wild shots, so my short game was really good today.”
English players Hannah Burke and Holly Clyburn are just about in touch for a final-day flourish, although Clyburn struggled badly on Friday as she followed up an opening 67 with an error-strewn 75 that included five bogeys.
They are tied on four-under, six shots off the pace, along with India’s Sharmila Nicollet and Chloe Leurquin of Belgium.
