Lucas Glover shoots 64, leads Jordan Spieth by one shot in the PGA Tour playoff opener

MEMPHIS, Tennessee: Sloppy mud one day, broiling heat the next. Lucas Glover is playing his best golf no the matter the conditions on the ground or in the air, posting a 6-under 64 on Friday for a one-shot lead over Jordan Spieth in the FedEx St. Jude Championship.
