ORLANDO, Fla. — Tyrrell Hatton felt the Arnold Palmer Invitational slipping away Sunday, perhaps unaware that everyone else trying to survive another brutal test at Bay Hill was feeling the same way.

He gave the wrong kind of salute to the 11th hole when he walked off the green after a double bogey cut his lead to one shot. It looked as though he was about to lose his mind.

Instead, he won the tournament with clutch play amid high stress, closing with seven straight pars for a 2-over 74.
