Scots surge into contention in Maryland

Norway’s Suzann Pettersen grabbed the lead with a super 67 and Scots Mhairi McKay and Catriona Matthew are also well in the hunt after at the halfway stage of the McDonald’s LPGA Championship at Bulle Rock in Maryland.

Pettersen, who came close to victory in the first major of the year at the Kraft Nabisco Championship in March, had seven birdies, including three in a row from the 15th.
