Woods was referencing the 2015 Masters, where McIlroy will be chasing the career grand slam and looking to extend his dominance of late in majors. McIlroy won this year’s British Open and PGA Championship, while Woods’ game was a mess all season, in part due to injuries. Woods missed the Masters and U.S. Open, wasn’t a factor at the British Open and then missed the cut at the PGA Championship.

McIlroy emphasized that Woods “wasn’t joking,” which is why it’s easy for him to stay motivated as Woods searches for his own motivation.
