I'll be honest I don't watch much golf, but I was amazed at how difficult this was. I only got 20/64 and left out some very popular players.
Anyway, here it is. No cheating/mulligans
Sporcle.com

It's a pretty cool site with all kinds of quizzes like this one.

I got 43.....missed some obvious ones though like Zach Johnson and Kenny Perry.

36/64, my trouble was spelling them all haha

WOW and i left out Mckelson... pretty bad

I got 34 and left out els, and furyk. cool site though...

I came up with 25, I could picture a ton more but could not remember their names for the life of me! Karlsson, Kaymer, Marksaeng, and Luke Donald were among them.

i only got 32 albeit I've been having some brewskies most of the afternoon regardless, the Aussies and South Africans KILLED me...its amazing how the little program psyches you out...I think AK was the highest ranked player I didnt get

That was my problem too. I'm not really familiar with a lot of players but after seeing the guys I missed, I realized how many more I should have gotten.

Cool quiz, I got 50 of the 64 which is actually pretty good I thought. I got the first 36 filled in and missed my first one with Graeme McDowell. I wasn't actually thinking as well I could have gotten some more toward the bottom if I remembered to think of the Match Play.

28 for me....amazing how blank my mind went

28 for though it would have been 33 if I could spell their names worth a darn.

got 44. the aussies drove me nuts, and forgot Justin Rose and Furyk! argh

got 46 my secong try, best player i missed, Paul Casey.

43 but I wasted time trying to get Miguel ANGEL Jimenez when it was looking for just Miguel Jimenez, I wrote Matt Goggin, it needed Mathew Goggin, I couldn't spell Baddeley correct apparently and same with Shwartzel because I couldn't get either one to register. So I really had 47.

I got 39, the spelling cost me a few too

44 here, misspelled Jimenez

Good quiz. 32 for me - the hardest bit is knowing which US player is further down the list. And spelling.

I got 44. I got all top 25 players except Anthony Kim!! I too spell many names wrong.
This was a great test!

I miss harrington because I couldn't spell his name, I knew the dutch guys but didn't even attempt to try and get those right

You only need to enter their last name. Sometimes you get a two-for, such as with Singh, Vijay and Jeev

I got 63, I forgot that Woods character.
