Phil Mickelson’s clubs for 2009 U.S. Open

Phil Mickelson Hybrid Bethpage 2 I had a chance to speak with Callaway Golf club designer Roger Cleveland in the company's massive tour truck this week. Cleveland mentioned that Phil Mickelson is using a new hybrid this week. Still in the prototype phase, the club was designed and conceived with significant input from Mickelson himself. Mickelson has previously used a Callaway FT hybrid in some tournaments.Cleveland would not go into detail about the club or specific technologies used in its creation, but Mickelson himself told reporters, "This is a special club I actually made, taking the back part of the hybrid out so that I can open it way up and get through that thick rough." (Click on the image for a better look at the club.)Like all prototype clubs, there is no guarantee Phil's new hybrid will ever make it to the pro shop. Here is a complete list of the clubs he is using at Bethpage:DRIVER: Callaway FT-9 (7.5°) Tour hosel with Mitsubishi Fubuki 73 X shaftFAIRWAY WOOD:  Callaway Big Bertha Diablo (15°) with Mitsubishi Fubuki 83 X shaftHYBRID: Callaway PM prototype (18°) with Mitsubishi Diamana Thump X shaftIRONS: Callaway X Forged (3-4), Callaway X Proto (5-9) with Rifle Project X 7.0 shaftsWEDGES: Callaway X Tour Forged (56°, 60°, 64°) with Rifle Project X 7.0 shaftsPUTTER: Odyssey White Hot XG #9 BladeBALL: Callaway Tour ix Follow David Dusek on Twitter(Photo by Sam Greenwood/Getty Images)
