MOBILE:-Catriona Matthew maintained her lead in the Airbus LPGA Classic on Friday with a second-round 67 that left her one stroke in front of teenager Charley Hull. England's Hull, playing on a sponsor's invitation, teed off early and grabbed the clubhouse lead with a 67. Overnight leader Matthew teed off shortly after Hull completed her round, and Hull wasn't surprised to see the Scottish veteran take advantage of the optimum scoring conditions to post a five-under 67 of her own. "It's a low-scoring golf course," Hull said. AFP
