With Titleist golf ball players making up 80 percent of the field at the U.S. Amateur, Titleist is also the tee-to-green favorite across every major golf club category.

From drivers, fairway metals and hybrids, to iron sets, wedges and putters, no less than 41 percent of the field in any major equipment category are placing their trust in the superior performance and consistency of Titleist equipment at one of the most prestigious events in amateur golf.
