Three of the four will also play the par three tournament together today.
Shane Lowry will begin his Masters journey at 3pm Irish time tomorrow.
He's been drawn alongside Max Homa and Kevin Na of the United States for the first two rounds at Augusta.
Elsewhere Padraig Harrington is among the early starters. He's in the second pairing of the day just after 1:10pm here, joined by amateur Austin Greaser and Canada's Mike Weir.
Seamus Power on debut has some star power in the shape of Patrick Reed and Lucas Herbert of Australia from 5:25pm Irish time.
Rory McIlory tees-off in the final pairing around 7pm Irish-time with Brooks Keopka and Matthew Fitzpatrick.
The Down man has been speaking about how the all-Irish practice round at Augusta National came about.
Shane and I spend a lot of time together down in Jupiter now that he and his family have moved down there.
So we organized that game last week. Then he texted me and said Seamus is going to join us, and that was great, and then Padraig as well. I actually didn't know Padraig was in the field, which is bad (Laughter). But I guess he played pretty well in the PGA last year.
Yeah, so it was really good fun. Shane and I and Padraig are going to play on the Par-3 tomorrow as well, so that will be good fun.
You know, the club here, it always is making little tweaks and improvements to the golf course, so there's always something to learn. The reason that I came up here a little bit early last week was just to see the couple of changes. 11 is basically a new golf hole. 15 is a little bit different. Then the three new greens, 3, 13, and 17, all with subtle little tweaks to the slopes there.
Yeah, you're always learning around this golf course. I don't think that ever changes.
