The second wave of golfers on course for the first round of the British Open at Royal Portrush Golf Club is making a surge up the leaderboard.
Brooks Koepka and Jon Rahm are at the forefront of the golfers challenging Shane Lowry for his spot on top of the tournament.
Lowry kicked off the tournament with a four-under 67, and only Rahm has been able to stay at that number from the afternoon session. Koepka and Tyrrell Hatton were at that number for a time, but then dropped shots on course.
Plenty of players, including six from the morning tee times, have reached three-under.
