It was a worldwide sweep for Titleist golf ball loyalists this weekend, as Ian Poulter, Tom Lehman, Stacy Lewis and Doug McGuigan all stood atop their respective leaderboards on Sunday! The four wins bring the 2012 Titleist victory total to 170, more than eight times the nearest competitor with 21. 

WGC: Titleist Pro V1x golf ball loyalist Ian Poulter closed with a 7-under par 65 to rally from four strokes back to win the WGC-HSBC Champions in Shenzhen, China.

Poulter carded eight birdies in the final round to finish with a 21-under 267 victory total, two shots clear of four players, including Titleist Brand Ambassadors Jason Dufner (Pro V1, 910D2 driver, 913Fd fairway metal, 906F2 fairway metal, 913H hybrid, AP2 irons, Vokey Design SM4 sand and lob wedges, Scotty Cameron putter) and Scott Piercy (Pro V1x, 910D2 driver, 913Fd fairway metal, 690MB/AP2 irons, Vokey Design SM pitching, gap, sand and lob wedges, Scotty Cameron GoLo putter). 

The win was Poulter's second World Golf Championship victory and the 14th of his professional career. Third round co-leaders and fellow Pro V1x loyalists, Lee Westwood and Louis Oosthuizen, shot identical final round scores of even par 72 to finish in a tie for sixth place.
