Park takes control in Ontario
Park In-Bee's round of 66 helped her keep ahead of the field after three rounds of the Manulife Financial LPGA Classic in Ontario.
Park, who won the 2008 US Women's Open, moved to 14-under-par overall with the five-under round, and stretched her lead to two shots over Brittany Lang (67) and Hee Kyung Seo (67).
"I haven't had a win for a while, so it [would] be nice to win tomorrow," Park said after her round. "But I'll just go out there, just play like today with no expectations, just play like a normal day."
The tournament caught up after losing time in the first two days to weather delays.
Lurking lower down the leaderboard, world number two Stacy Lewis is eight-under-par after three rounds, on the same score as talented teenager Lexi Thompson.
