There’s a fun story from the 2007 Walker Cup at Royal County Down in which Rory McIlroy and Billy Horschel, both not yet 21, faced off in three of four matches.
During one of the foursomes sessions, Horschel hit a bunker shot and sprinted toward the hole to see if it would drop in, yelling “Go in! Go in!” the entire way. McIlroy didn’t care for the antics, and a day later he opened their singles match with an eagle and unleashed a thunderous yell.
“Ohh, I absolutely despised him,” McIlroy said on GOLF’s Subpar a couple of years ago. “We’ve actually become really close since, which is great. We were all probably obnoxious at the time, but because I was at home as well and he was like pretty rude to the crowd at times too and they are my people. It was like, ‘I’m going to beat his ass.’ But we actually have forged a really good friendship since. Billy’s a good dude. I like him a lot.”
OK, so what’s the point of revisiting this moment in time? It’s just a reminder that while the Walker Cup is a highly competitive and entertaining amateur event, it’s also a chance to watch and get to know a handful of guys who might very likely play in the pro ranks and on your TV screens someday.
