Feng goes four clear in Dubai
China's Shanshan Feng moved four clear of the field at the Dubai Masters as the race for the Ladies European Tour money list title hotted up.
World number six Feng added a seven-under-par 65 to her opening 66 to reach halfway at the Emirates on a superb 13 under par.
The first Chinese golfer to win a major - that came at the LPGA Championship in June - heads into the weekend with England's Felicity Johnson as her closest challenger.
Four players are one stroke further back and they include German Caroline Masson, who needs a top-three finish to have a chance of denying Spain's Carlota Ciganda the Order of Merit crown.
Ciganda matched Masson's 68, however, to be only two shots behind her on six under.
Feng, joint overnight leader with England's Florentyna Parker, took control with seven birdies in the first 12 holes of her second round.
The 23-year-old did then bogey the short fourth - her 13th - but came straight back with yet another birdie and parred her way in.
Johnson, twice a winner in Europe since turning professional six years ago, completed her 67 with an eight-foot birdie putt on the long 18th.
That relegated Masson, American Cindy Lacrosse and French pair Gwladys Nocera and Joanna Klatten into joint third.
"My putting was really good," Feng said. "I think I have learned something from (South Korean) Inbee Park, who is our money queen on the LPGA Tour this season.
"I have played with her many times and know how well she putts.
"My low score of the year was only six under and today I've managed to break that."
Defending champion Lexi Thompson is six back following a 68.
"If I can shoot five or six under on the weekend that will put me in a good position," the 17-year-old American said. "You can make a lot of birdies out there and hopefully I've saved them for the weekend."
Johnson said: "I hit the ball great again, so am very happy with my work so far this week.
"It's always nice to finish with a birdie. I missed a really good opportunity on 17, but hit a good shot into 18 and just kind of snuck it in the left edge.
"I knew when I was standing there if it went in I would be in the last group, so it gave me a little bit more to focus on.
"The last four to five months I've worked hard on my short game and especially on my putting really. We're going to a good place with it hopefully."
Masson, who was paired with Ciganda on the opening two days, said: "I just want to keep playing well, make some birdies and just try to win the tournament.
"If she plays really well I can't do anything about it."
Ciganda commented: "I think it's a big thing, but I'm just trying to stay in the moment and play my own game.
"I don't really think about the result or the Order of Merit."
