Hye-Jin Choi holds a one-stroke lead heading into Sunday's final round at LPGA Shanghai. The South Korean fired a 3-under 69 in the third round to maintain her tournament-long advantage over the field. Choi has controlled the event from the start and now sits on the brink of a victory. She'll need to hold off challengers in the final 18 holes, but her consistency through 54 holes puts her in position to close it out. The LPGA's Shanghai stop wraps up tomorrow with Choi as the favorite to claim the title.
