Pour some more coffee because the 150th Open Championship is well underway with most of the East Coast of the United States just waking from their slumber and starting to tune in. The best golfers in the world began their quest for glory and a Claret Jug at 1:35 a.m. ET with play beginning on the historic Old Course at St. Andrews for this unique and memorable tournament.

Collin Morikawa, the reigning Champion Golfer of the Year, was joined by Xander Schauffele and Rory McIlroy, two of the hottest players over the last couple of months, in a feature group to start the day. McIlroy has led the trio in terms of his contention, going bogey-free across his front nine to rocket up the leaderboard as he continues to seek his first major championship since 2014.

Not all the marquee names are off in the morning hours as fans will be able to watch the likes of Tiger Woods, Matt Fitzpatrick and Max Homa at 10 a.m. They precede the threesome of Jordan Spieth, Jon Rahm and Harold Varner III, which is sure to be a popular group as well. Woods' rounds this week at St. Andrews are must-watch affairs given this may be Tiger's last legitimate chance to win an Open at St. Andrews.

Unlike other championships this year, the wind appears relatively steady throughout the day and neither the morning nor afternoon tee times will receive a considerable edge. Scotland weather can flip on a script, but if the forecast remains true, players will be presented ideal scoring conditions in the opening round at the Old Course.

Here's a look at every group starting in the first round of the 150th Open at St. Andrews. Be sure to check out the complete Open TV schedule and coverage guide so you can learn how to watch all week, and don't miss live Open leaderboard coverage throughout Round 1. All times Eastern
