Matthew in contention

Scotland's Catriona Matthew continued her superb fightback to move into contention at the Kraft Nabisco Championship on Friday.

Matthew was four over par after six holes of her opening round in California after two early double bogeys, but responded with four birdies to shoot an opening 72.

Another four birdies coupled with no dropped shots saw the 44-year-old former Women's British Open champion record a second round of 68 to lie four under par in the year's first major championship.

Matthew, who was second in this event in 2007, was three off the lead held by American Lexi Thompson and Korea's Se Ri Pak, with Thompson also on the comeback trail after an opening 73.

The 19-year-old was still one over par for the tournament after five holes of her second round, but then birdied eight of the remaining 13 holes to card a flawless 64.

Pak's second round was far more sedate, birdies at the second and 18th seeing the five-time major winner add a 70 to her opening 67.

American Michelle Wie was a shot behind on six under after adding a 71 to her opening 67, while overnight leader Shanshan Feng of China was also six under having yet to start her second round.
