Patty Tavatanakit, Jake Knapp take Grant Thornton lead

Patty Tavatanakit of Thailand and Jake Knapp birdied the first nine holes they played and added a late eagle on their way to the first-round lead at the Grant Thornton Invitational on Friday at Tiburon Golf Club in Naples, Fla.

The mixed team event featuring PGA and LPGA Tour stars employs three different formats over three rounds. In Friday's scramble format -- in which both players hit each shot and select which ball they'll use for the following shot -- Tavatanakit and Knapp put together a 14-under-par 58.
