US PGA champion Collin Morikawa will take a two-shot lead into the final round in Florida as the American goes in search of a first World Golf Championships title at The Concession.

The 24-year-old carded a 67 to sit at 15 under at the WGC-Workday Championship and he could have been out of sight after a run of seven birdies in eight holes from the fifth handed him a five-shot lead.
