John Rahm to celebrate being a new dad with the green jacket.
As for the HIO, lol, had to Google that for a look-see..... there have been only 30 of them in the history of the Masters. Two last year on the 16th hole which accounts for 21 of the 30 in history. The 4th hole has just one HIO in history and that was 29 years ago. If it happens, it's most likely om the 16th where J. Thomas and B. DaShampooDude did it last year.
I'll go with Justin Thomas to strike lightning twice.
