Alena Sharp remembers quite well the first time she played golf with Brooke Henderson. It would be tough to forget considering the teen phenom made a hole-in-one.

“I said, ‘Hey, when you become of age, you owe me a drink,'” Sharp recalled as the two Canadian golfers met with media ahead of this week’s Olympic women’s golf competition just outside of Paris.

That fateful ace began a friendship and mentorship that has spanned more than a decade and spawned a Canadian golfing duo that is entering its third Olympic Games together.
