It's been 32 years since the U.S. Open was last contested at Merion Golf Club's famed East Course. Designed by Hugh Wilson, Merion sits on a modest 120 acres outside of Philadelphia. The East Course will play a shade under 7,000 yards this week, diminutive by modern U.S. Open standards.

Merion will present a very difficult, but an infinitely fair test of golfing skill. And with precision at a premium, it's no surprise that 97 players are trusting their chances for a U.S. Open title to a Titleist golf ball, more than four times the nearest competitor with 23 and more than all other golf balls combined.

In fact, 2013 marks the 65th consecutive year that Titleist has been the #1 golf ball of choice at the U.S Open Championship.

Titleist also tied for first in iron sets this week (37), and was an overwhelming favorite in the sand, lob and approach wedges category (159).
