The toughest test in women's golf, the U.S. Women's Open, is underway at Pine Needles Lodge & Golf Club in Southern Pines, N.C. This marks the 77th time that the oldest of the LPGA Tour's five majors will be contested and once again, Titleist is the overwhelming golf ball of choice. Over 80% of players in the field will be pinning their hopes for victory on a Pro V1 or Pro V1x golf ball.

Why do so many of the world's most skilled players rely on the #1 ball in golf? Check out the videos below to hear from the players in their own words, including Jessica Korda,  Danielle Kang, Lydia Ko, So Yeon Ryu and more.
