It looks like Jason Day is using a G425 and Mizuno irons. It’s always interesting to see guys drop the clubs from the brands they used to play.
For the most part it’s pretty constant what they play when off contract. Lots of Taylor made in the woods (ping has been gaining a large share though), mizuno irons, vokey wedges, and circle t for the putter.
I’m interested to see what clubs he keeps in the bag for 2021 ...he’s one of my favorites out on tour ..followed him for a little bit at the Houston open and enjoyed listening to he and his caddy talk over shots
