PGA Tour rookie Shawn Stefani aced the 17th hole on Sunday at the U.S. Open, making him the first golfer to hit a hole-in-one at any Open at Merion Golf Club in Ardmore, Pa.
The 31-year-old Stefani has an MLB.com logo on his bag after agreeing to a sponsorship deal in May.
His historic shot Sunday bounced out of the rough and rolled about 50 feet toward the cup. Stefani said he could tell by the crowd's reaction that it had gone in.
"I didn't know what to do but jump up and down for joy," Stefani said, according to The Associated Press.
After the ball went in, Stefani walked the length of the 213-yard par 3 and kissed the sweet spot where it landed, according to the AP report.
He did not donate the ball to the USGA Museum, but instead donated a signed glove and scorecard. Merion is hosting the major tournament for the fifth time. Stefani was under par for the day, but finished the tournament at 19 over par.
