for the record, i'm not sure this is the best move. But whatevs...it's entertaining.
Also, both Eric Hosmer and Kila are trending. wow.
You hate Hosmer, just come out and say it. 
nahh, i'm more of a Kila apologist. imo, I don't think the Royals can contend this year, and we haven't given Kila enough PA's. I hope they prove me wrong though.
I'm really excited about Hosmer though..
Pitchers have figured out you just don't throw Kila fastballs. He swings away at breaking balls out of the zone. He was really never a huge batting average guy in the minors. Walked a lot and hit home runs was his game, which is a rare combo, but in the minors you can get away with doing things against pitchers that pitchers don't do at the major league level in terms of deception, pitch mixing, and control.
Hosmer pretty much forced their hand. A .439 hitter with some pop just can't be kept down on the farm. I think they wouldn't have minded bringing him north out of spring training, but he wasn't on the 40-man and they didn't want him to be anything more than a super 2.
As it stands, the offense is improved. The defense is improved. And the fans are getting excited. I'm sure its no coincidence that they call him up today so they can play him tomorrow night on Buck Night/Fireworks Friday when you can expect to get a larger than average crowd. There will be a huge walkup. I know I'm considering heading over.
