Ahhh, baseball. I've been waiting since October for baseball to return. Spring training's happening right now, my fantasy baseball draft happens next week (let's goooo, BILFs!), and hot baseball players are using questionable grammar. Today's example is Pat freakin' Burrell: former Phillies ballplayer, current Tampa Bay Ray, always a player.Pat did a very, very nice thing: He took out some ad space in the Philadelphia Daily News, and he wrote a thank-you letter to the Philly fans who, um, booed him for a good portion of his career in Philly. This was a sweet gesture. It would have been even sweeter had he called himself a ballplayer as opposed to a ball player... 
Now, I'm not saying that using the phrase ball player is entirely wrong. I don't think it's dead wrong. However, after a lot of Googling, I found that people definitely use the term ballplayer more often than ball player. The term ballplayer is also in the dictionary, which means it's actually a real word/term. I think ball player has become socially acceptable terminology, but I don't necessarily think that, given the choice between using ball player and ballplayer in a sentence, ball player would really be the best term to use.
Then again, Pat (in the Rays uniform, on the left) might really have literally meant he's a, um, ball player...
I originally found this picture over at Deadspin.
Ahhhh, good ol' Pat. I'll miss seeing him (and his nice butt) in red and white pinstripes this season, but now I have an excuse to watch Rays games. (He looks just as nice in a Rays uniform, and now Tampa Bay, not my Phillies, must contend with his slowness.) BILFiness* knows no team-related bounds; I may be a Phillies girl at heart, but dammit, I'm a sucker for a hot baseball player no matter which team's uniform he happens to be wearing. (And yeah, BILFs even manage to retain their cuteness when they're messing with their junk on the field.)* "BILF" is my very own made-up term to describe cute baseball players. It stands for Ballplayers I'd Like [to]...um, there are several "F"-words that could fit here, so pick your favorite. I know what my favorite one is... "The BILFs" is also the name of my fantasy baseball team.
