Rory McIlroy aced the par-3 15th hole Thursday at Spyglass Hill Golf Club in the opening round of the AT&T Pebble Beach Pro-Am.

Rory McIlroy has suggested that the PGA Tour could scale back the number of tournaments it stages each year in order to combat “fatigue” among golf’s fanbase.

McIlroy makes his season debut on the U.S.-based circuit this week at the AT&T Pebble Beach Pro-Am, one of the tour’s $20 million signature events. It’s a big week—or at least it’s supposed to be, with a limited field of 80 players that includes 45 of the top 50 in the world playing one of the most iconic courses on the planet.
