July 25 (Reuters) - American Lizette Salas, bidding for a second LPGA title, made a fast start and strong finish to take a commanding four-shot lead after the third round of the Meijer LPGA Classic in Grand Rapids, Michigan on Saturday.
The 26-year-old from California birdied three of the first four holes, and three in a row in the last five, to fire a sizzling seven-under-par 64 in bright sunshine at the tree-lined Blythefield Country Club.
