Justin Rose was so caught up in winning the Olympic golf’s first gold medal in 112 years that he forgot about an important memento from the historic occasion. 
His golf ball. 
Rose made a 3-foot birdie putt on the 18th hole. He thrust his fist in the air. He popped the British crest on his shirt. He embraced silver medalist Henrik Stenson. He took his place on the podium and sang heartily to "God Save The Queen" as the British flag was raised. 
All the while, he never retrieved the ball from the cup. 
Daniel Neves, who works for a Brazilian golf federation, said a photographer noticed the ball was still in the cup well after the ceremony.
"He gave it our media chief who showed it to Justin and said, 'Hey, we have something for you,'" Neves said. "Justin said, 'Yes, that's my ball.' We offered it back to him, but he signed it and gave it back to us." 
Neves said the golf ball will be put on display at Olympic Golf Course, and he hopes the woman who wins gold this week might be willing to do the same.
