This week the golfing world turns its attention to The Golf Club at Dove Mountain in Maranza, Arizona, where the best players in the world are battling for the first World Golf Championship title of the season at the WGC-Accenture Match Play Championship.
You never know what might happen in match play and upsets have already been a big part of the early story as preliminary matches got underway on Wednesday. However, one thing that has never been in doubt this week is the golf ball of choice.
Titleist golf ball players account for 33 competitors in the elite 64-player field at this year's Match Play, three times the nearest competitor with 11 and more than all competitors combined.
Titleist was also the field favorite in the irons (17) and sand, lob and approach wedge (53) categories.
