ARDMORE, Pa. (AP) -- Shawn Stefani lost track of the ball as soon it rocketed off his 4-iron.
A roaring U.S. Open gallery tracked it for him.
"Go! Go! Go! Go!"
It did Sunday when Stefani aced the 17th hole, making him the first golfer to make a hole-in-one at any U.S. Open at Merion Golf Club, which is hosting the major for the fifth time.
"When the crowd went crazy, I knew it went in," he said.
His shot bounced out of the rough and rolled some 50 feet toward the pin before falling in the cup.
Stefani raised his arms and hopped around the tee in celebration. Caddie Chris Callas gave him a playful hug and a slap on the back.
"I didn't know what to do but jump up and down for joy," Stefani said.
Then he walked down the 229-yard, par-3 hole and planted a kiss on the sweet spot where it landed.
