Luke Donald admits he had never even heard of the guy that won the Wells Fargo Championship

On Sunday at the Wells Fargo Championship, Derek Ernst outlasted David Lynn to win his first ever PGA Tour title.

Don't feel bad if you've never heard of the 22-year-old, ranked 1207 in the world before his playoff win on Sunday, because you aren't the only one.

After the win, Luke Donald, ranked No. 5 in the world, tweeted the following message letting everyone know he was a little in the dark as well.

Never heard of Derek Ernst until this week, shows how deep the fields are on the PGA Tour, welcome to the winners circle #GoodForHim

If you think Donald was saying anything negative about the guy, he pointed out in a response to a follower that he was simply admitting that the fields these days are so deep that a guy nobody has ever heard of can beat the likes of Phil Mickelson, Rory McIlroy and Lee Westwood.
