Rory McIlroy has been grouped with rising star Jon Rahm for the opening two rounds of the 81st Masters.
McIlroy will be accompanied by the big-hitting Spaniard and WGC Match Play semi-finalist Hideto Tanihara in the third last group out on Thursday, with world No 1 Dustin Johnson out in the final group of the day alongside two-time champion Bubba Watson and Jimmy Walker.
The 27-year-old's latest bid to complete the career grand slam begins at 6:41pm (BST) on Thursday, and they are out three hours earlier for the second round.
"I've played with a few of the Asian contenders, so I sort of expected one of those guys," said McIlroy. "And then Jon Rahm, I haven't played with him competitively. We played 18 holes, a practice round, in Austin, and I'm really impressed with his game.
"He's a great young player, and he'll be a huge asset to our European Ryder Cup team in years to come. I'm looking forward to it."
Masters tradition dictates that the defending champion plays with the US Amateur champion, so young Australian Curtis Luck has the honour of being out with Danny Willett while Matt Kuchar makes up the threeball.
Jordan Spieth, whose infamous meltdown at the 12th was the key moment of the 2016 Masters, heads out in group No 14 with European Ryder Cup team-mates Martin Kaymer and Matt Fitzpatrick, who closed with a final-round 67 last year to earn a top-10 finish and guarantee an invite for this week.
There is a clash of form in the 25th group of the first day as Open champion Henrik Stenson looks to shake off a poor run of results over the last month, and the Swede partners in-form English debutant Tyrrell Hatton and veteran 2009 champion Angel Cabrera.
Daniel Summerhays has the honour of striking the first drive at 1pm (BST) on Thursday, shortly after Jack Nicklaus and Gary Player hit their ceremonial tee-shots which officially open the tournament.
