Northern Ireland is part of the United Kingdom, but it's not on the island of Great Britain. So why is it hosting the “British” Open this week?

W orld No. 1 Scottie Scheffler, Shane Lowry and Collin Morikawa are grouped together for the first two rounds of the 153rd British Open, beginning July 17 at Royal Portrush, in Northern Ireland. They will tee off in the first round at 5:09 a.m. (EDT) and in the second round at 10:10 a.m.
