Maybe it's just one round, but Thursday at The Open, 50-somethings Lee Westwood and Phil Mickelson shot under par.

The Open Championship 2025 had a contingent of 19 LIV Golf pros, but eight of them missed the cut. While Tyrrell Hatton, Lee Westwood, Marc Leishman, and Jason Kokrak were in contention, big names such as Brooks Koepka, Joaquin Niemann, and Cameron Smith failed to make it to the weekend at Royal Portrush.

Phil Mickelson handed out a signed glove and ball to his playing partner Ryan Peake after the pair competed alongside each other in the opening round of The Open Championship. Peake played his way into The Open after winning the New Zealand Open earlier this year.

Phil Mickelson and Lee Westwood are offering reminders that the British Open doesn't discriminate against older players.

Phil Mickelson got a horrible break early at the 2025 Open Championship but saved himself with a bunker hole-out to briefly take the lead.

The 153rd Open Championship, at Royal Portrush, Northern Ireland, runs Thursday, July 17, through Sunday, July 20.

Phil Mickelson is expected to make the cut at this year's Open Championship at Royal Portush in Northern Ireland and keep his slim hopes of winning a seventh major title alive
