Bill Haas leads the Masters by one shot after firing 4-under 68 on Thursday. The five-time PGA TOUR winner hasn't made any notable equipment changes this season, but he did make an adjustment to his Titleist 913D2 driver last week at the Shell Houston Open.
Looking to knock spin off his driver, Haas opted for a new Aldila Rogue 70TX shaft with a lighter screw and B1 setting on the Titleist SureFit hosel. The changes lowered the spin and gave Haas the flight he preferred. Haas only missed one fairway (13 of 14) during the first round.
Here's a look at the rest of the clubs in his bag.
