Following the tournament’s conclusion, golf insider Dan Rapaport listed several big-name golfers who failed to make a top-10 spot in any of the majors this season.One day after Scottie Scheffler clinched the 2025 Open Championship title, Rapaport shared a tweet that read,“Justin Thomas, Patrick Cantlay, Sepp Straka, Collin Morikawa, Joaquin Niemann, Brooks Koepka and Cameron Smith combined to post *one* top 10 in the majors this year.”Agreeably, the only golfer on Rapaport’s list who made a top-10 spot in a major tournament this season is Joaquin Niemann.
