Jordan Spieth has worked alongside caddie Michael Greller for over a decade. He knows his swing, his tendencies, and exactly what his game is missing. In this iron fitting session at the Titleist Performance Center, Spieth and master fitter JJ Van Wezenbeeck put Greller through a full Titleist T-Series iron fitting - analyzing launch angle, land angle, distance gapping, and set composition. The result: a blended set built around the new T250 irons and GT1 hybrid, giving Greller the ball flight, stopping power, and consistency his game has always needed. These are the same tools trusted on Tour - built for every dedicated golfer.
