He is now one of only 14 players to win six or more majors. Mickelson's last victory came in 2019 when he won the 2019 AT&T Pebble Beach Pro-Am. "I mean this is just an incredible feeling because I just believed that it was possible but yet everything was saying it wasn't," Mickelson said after accepting the trophy. "I hope that others find that inspiration — it might take a little bit extra work, a little bit harder effort to maintain physically or maintain the skills but gosh is it worth it ... and I'm so appreciative to be holding this Wanamaker trophy."
