Winner's bag: What Jason Day used to become World No. 1

Once again Jason Day had almost every part of his game working, but although he led the field in driving distance, he was T-50 in accuracy. That makes hitting 75 percent of his greens in regulation (ranked T-6) with his TaylorMade RSi TP irons even more impressive.

Here's what he had in the bag at the BMW Championship at Conway farms G.C., Lake Forest, Ill:

Ball TaylorMade Tour Preferred X

Driver TaylorMade M1 460 (Mitsubishi Kuro Kage Silver TiNi 70x), 10.5 degrees

4-Wood TaylorMade AeroBurner, 16.5 degrees

Irons (2) TaylorMade RSi 2; (4-PW) TaylorMade RSi TP

Wedges TaylorMade Tour Preferred EF (47, 52, 58 degrees)

Puttter TaylorMade Ghost Itsy Bitsy Spider prototype
