Rory McIlroy’s Irons Are 1° Upright. Tommy Fleetwood’s Are Flat.
This is from TaylorMade’s bag-swap video — Rory and Tommy playing a 3-hole match with each other’s clubs.
They get into iron lie angles.
Tommy’s irons are slightly flatter than standard. They get less flat as the clubs get shorter, in half-degree increments.
Rory plays 1° upright. He said his swing tends to leave the toe down at impact.
That’s not a small detail. When they swapped bags, the difference showed up immediately — start lines, turf interaction, and how the clubs felt through the ground.
Tommy’s flatter setup is specific to his swing and how his irons sit at impact. He credits Adrian and his team for those specs.
One degree either way is enough to make another Tour player’s irons feel wrong.
Recommendation: get fitted by someone like
