Royal Portrush showed its teeth on Thursday as the 2025 Open Championship field got the full links golf experience. The weather shifted and changed throughout the first round to create challenging scoring conditions,

Spieth entered Portrush with four straight top-25 Open finishes, so there should be plenty of confidence that he turns in a much better round on Friday. Making up a six-shot deficit will be tough, but if Spieth can get to even-par, or even one-under, he'll have a shot to get into the top 10 before the weekend.

The second round of the British Open will begin at 1:35 a.m. (EDT) on July 18, when 2009 champion Stewart Cink, Matteo Manassero and Marc Leishman tee off.
