Mahan the man to catch in Miami

Fourteen birdies between them in just 10 holes were still not enough to make Europe’s world leaders Martin Kaymer, Lee Westwood and Luke Donald the overnight pacesetters in Miami.

Kaymer and Donald both stood five under par and Westwood four under at the end of a storm-shortened opening day at the WGC-Cadillac Championship, but American Hunter Mahan had raced into a two-stroke advantage on seven under after 11 holes.
