The Scottish Open has become one of the big events on the golf schedule ever since it became a partner event between the PGA Tour and the DP World Tour, as the best players from both tours come together for a chance to play some links golf in preparation for the Open Championship a week later.

"I definitely finished the round better than I started it," said McIlroy, who closed the first round with three consecutive birdies and is 2-under going to Friday.

With a victory this week, MacIntyre will become the first player to win back-to-back Scottish Opens.
