Clark shared the 36-hole lead at Bay Hill a year ago and finished second. Lowry shared with 54-hole lead with Scheffler and finished third. Last year was the first time Lowry and Clark broke 70 at Bay Hill, so they appear to have figured something out.

Lowry began the day with a two-shot advantage, but struggled to an error-strewn 76 at Bay Hill which left him at four under par.

Collin Morikawa made a 12-foot birdie putt on the 18th hole Saturday on a baked out Bay Hill course for a 5-under 67, giving him a one-shot lead in the Arnold Palmer Invitational and a chance to win for the first time in 17 months.
