The 2019 British Open kicks off Thursday, and for those stateside hoping to get a peek at golfers working their way through historic Royal Portrush, it’ll be a very early morning.

Local hero Darren Clarke will get the honor of teeing off first at 6:35 a.m. local time, which will be 1:35 a.m. on the East Coast as competition for the Claret Jug begins.

(No wonder Tiger Woods began his sleep-training regimen in the hopes of winning the 148th British Open.)
