RICHMOND, Texas — Lorena Ochoa and Jiyai Shin will settle their duel for LPGA Tour player of the year on the final, frantic day of the season.

Kristy McPherson finished off a 5-under 67 in fading sunlight Sunday to move to 8 under and take the lead in the LPGA Tour Championship before the second round was suspended because of darkness.

Shin was one stroke back with two holes to play in her second round; Ochoa was two back with one hole left. Players will resume the second round today, and the top 70 and ties will immediately begin the final round.

For Ochoa to win her fourth straight player of the year title, she must win or finish no worse than third and then hope Shin places out of the top 10. The two are also decimal points apart in the race for the Vare Trophy, awarded for the season’s lowest scoring average.

“Tomorrow, everything will be answered,” Ochoa said. “I am very excited, yes.”

Shin is trying to become the first player since Nancy Lopez in 1978 to sweep the money title, rookie and player of the year and the Vare Trophy.

“I have a good shot at it,” Shin said. “It’s going to be very close. It will be the most important day of my life.”

The 28-year-old McPherson is just looking for her first LPGA Tour victory. She picked up five birdies without a bogey in her second round after a 69 on Thursday.

She’s one of the few players who completed two rounds without interruption.

“Our goal was to get in before the sun went down, so we were happy to do that,” she said. “We were fortunate to get through.”

So far, the weather has been the major story of the tournament.

Heavy rain swamped the Houstonian Golf and Country Club on Friday and Saturday, forcing organizers to cut the event to 54 holes. The fairways were still water-logged Sunday, so players were allowed to lift, clean and place.
