Who surges, who struggles and who wins on Sunday at the U.S. Open

BROOKLINE, Mass. — There has been drama at this U.S. Open from the moment players arrived on property. Before it started, it wasn't about the golf. It was about the state of golf. Now, it's about the golf, with a leaderboard that has a mix of stars, up-and-comers and a few who-are-they contenders.

He shot 62 on Sunday last week in picking up a victory at the RBC Canadian Open, 68 in the final round at the PGA Championship and 64 on Sunday at the Masters.

Michael Collins: Jon Rahm still believes he's the world No. 1. He's the defending champ and wants to do what Rory did last week but to an even stronger field — remind them who the best is. And when he starts «feeling it», he is going to make some loooong putts because that's what he does.

Kevin Van Valkenburg: Rahm. It hasn't been the season we all thought it might be for Rahm, but he still has the most complete game of those three. The putter is heating up — finally. Scheffler and McIlroy can get streaky, and that includes making a bunch of bogeys when it
