​Andrew Coltart has admitted that he was taken aback by just how relaxed Scottie Scheffler seemed to be on Monday at Royal Birkdale having missed the cut at the Scottish Open this past week. Scheffler is likely to be the favourite to win The Open Championship. The world number one is the defending champion following his victory at Royal Portrush 12 months ago.AdvertisementAdvertisementAdvertisementHowever, the 30-year-old is hardly firing on all cylinders this season.Scheffler has not won since his first start of 2026, at The American Express. Meanwhile, he goes into the final major of the year off the back of his first missed cut since 2022.Scheffler has flirted with missing the cut on a couple of occasions this year, most notably at the Genesis Invitational when he holed an extremely crucial putt on the 18th green during his second round.But it was arguably one of the stories of the season when Scheffler did complete Friday’s round at The Renaissance Club.Photo by Michael Reaves/Getty ImagesInterestingly, it does not appear to have prompted Scheffler to begin an inquest into where his game is at ahead of The Open Championship.AdvertisementAdvertisementAdvertisementSpeaking on Sky Sports about Scheffler’s demeanour at Royal Birkdale, Andrew Coltart suggested that he was extremely impressed by the American.“One win, four second place finishes, I saw him doing a bit of work with our colleague Josh over there in The Open Zone earlier on, I’ve never seen Scottie Scheffler so relaxed,” he said.“I thought he was going to be the opposite. I thought there was going to be a little bit of frustration creeping in because of that missed cut last week. He gave himself an extra couple of days to come down, and I don’t think he’s overdone it. I just think he’s learned about the nuances of this golf course, and he looks like he’s in fine fettle.”Scheffler will be playing alongside Bryson DeChambeau and Tyrrell Hatton over the first two rounds in Southport.AdvertisementAdvertisementAdvertisementOf course, no one is under greater scrutiny heading into The Open than DeChambeau. LIV Golf’s talisman has missed the cut at all three of the majors so far this season.The Open has not been particularly kind to DeChambeau over the years. Both of his top 10 finishes have only come about after a charge on Sunday. He has never really contended at the event.So many will be tipping DeChambeau to make an early exit once again over the next few days.And Coltart believes that the two-time US Open champion seems to be struggling to work his way out of his current rut.“It’s interesting. I don’t know, I think he’s not happy with his equipment. I think he’s muddling about with his equipment, he’s very, very technical with his equipment, his 3D printed clubs, and I don’t think he’s got the matchups quite right. Obviously, that’s affected his confidence,” he said.AdvertisementAdvertisementAdvertisement“I saw him on the range earlier on today
