J.B. Holmes heads into Friday's 2019 British Open second round at the top of the leaderboard at Royal Portrush in Northern Ireland.
The 37-year-old carded a five-under par 66 on Thursday to take top spot by one shot from Ireland's Shane Lowry.
There are a host of big names two shots off the lead. Brooks Koepka, Jon Rahm, Sergio Garcia and Tony Finau are all well-positioned ahead of the second day of action.
However, pre-tournament favourite Rory McIlroy and three-time champion Tiger Woods are in danger of missing the cut after struggling on Thursday.
