Who can still win the Masters? After 18 holes at Augusta National, here's what history tells us:
Nine of the past 11 Masters champions opened with a round in the 60s.
That's good news for the likes of Brooks Koepka, Phil Mickelson and Tiger Woods. But for Rory McIlroy, who opened in 1-over 73, his career grand slam chances took a slight hit.
The past 13 Masters champions were each inside the top 10 after the first round.
Tiger Woods was T-11 after Thursday, as was Rickie Fowler and Jason Day, so this isn't the kind of stat Woods wants to see.
