SHANGHAI (AP) — Alexander Levy birdied his opening three holes and kept right on going to a 9-under 63 and a four-shot lead in the BMW Masters. Levy had a big smile on another damp, overcast day as he piled up birdies, including a 40-foot putt down a steep ridge that curled into the left side of the cup on the sixth hole, and an approach that plopped down a foot from the cup on No.
