The trio of Rory McIlroy, Jon Rahm and Justin Rose all have work to do in the second round of The Open at Royal Liverpool.
In one of the marquee groups on Thursday, Rahm and Rose shot opening 74s and they must take advantage of any favourable conditions on Friday morning to swiftly get themselves up the leaderboard.
They play alongside McIlroy who, after his victory at the Scottish Open last week, arrived at Hoylake full of confidence. His best golf did not appear as he got his Open bid up and running, but a crucial par save at the 18th hole saw him card a level par 71 and leave himself only five shots back of the lead.
Tommy Fleetwood is one of those who sits top of the leaderboard, delivering in front of his home fans. He posted seven birdies in his 66 to set the early pace, with Emiliano Grillo and amateur Christo Lamprecht also at five-under.
Brooks Koepka, Scottie Scheffler and Viktor Hovland are among a host of big names at one-under par and still firmly in the hunt for major glory.
