Tyrell Hatton overcame high winds and jittery nerves to capture his first PGA title and fifth worldwide. Hatton kept it together down the stretch by playing bogey-free over the last seven holes for a 2-over 74 to win the Arnold Palmer Invitational by one shot over Marc Leishman .  The scoring average Sunday was 75.06, the toughest final round at Bay Hill since 1983. Hatton’s 284 was the highest score to win the Arnold Palmer Invitational since it began in 1979.
