It's promotion time in my mind.  Disco, Nicoll and Bianchi don't have a whole lot more to prove at their levels and really no one standing in their way to be upped a level.  Some of the bigger names are slowly but surely getting better.  Kila and Hos have raised their average to .250 while Moose hit another HR last night after a slight Homer drought and extending his hitting streak to six games.

Eric Hosmer

Eric has raised his average to .250 coming into todays game.  In comparison Moustakas didn't cross the .250 boundary until July sometime.  I don't expect a HR title out of Hos but I would expect alot of doubles and maybe a higher overall line than Moose considering Hos has better plate discipline.

.250/.365/.354 7 doubles 1 HR 18BB/27So

Kelvin Herrera got skipped in his second start for the Bees.  Hopefully it is nothing serious.
Blaine Hardy has a nice 35/0 K/bb ratio

Burlington Bees stats

Clint Robinson has continued his hot hitting in Wilmington ranking in the Top 5 of almost every offensive category in the Carolina league.  Jason Taylor will be reinstated in about 25 games or so and if he(Jason) is gonna get to play this season then giving Robinson a promotion to AA at that time could make sense if he continues his hitting ways.  This is probably the best Wilmington hitting performance by a Royal prospect since Dee Brown.
Moustakas hit his 5th Hr last night and Jeff Bianchi has proven enough to get promoted in my mind. 
Giavotella might be the winner of this year Ka'aihue AWARD for most disciplined hitter in the minors.  Little Italy is carrying a .347 OBP despite only hitting .200.  Hopefully that BABIP starts to balance out and he raises that average soon.
Juan Abreu made his first appearance of the year the other night for the Rocks and while he did give up a run Abreu continued his strike out ways.  Abreu had a 12.59 K/9 line last year in Burlington and fanned the side in his first appearance with the Rocks.
Danny Duffy dominated in his last start.  Tonight he faces the First Place Lynchburg Hillcats(Pirates) who feature the '08 2nd overall pick Pedro Alvarez.

NW Arkansas has some solid performers who might be pushing for promotions.

Jordan Parraz is proving to be a wise pickup for Tyler Lumsden.  His current line is .347/.443/.505 10bb/10so.  He's showing more pop in the last 10 games hitting 6 doubles and both of his HR's.  Parraz needs to play for a while longer in AA before he is ready to be promoted but it is nice to see him performing well.
Chris Nicoll I don't know what else Chris needs to do to show he is better than this level.  He's got a Whip under 1 19 K's in 20 IP and his FIP and ERA are down over a run each compared to last season.  PROMOTE NOW !
Chris Hayes I might as well just type the same thing that I did about Nicoll.  Disco is dominating, it's just a different type of domination and the scouts and management probably can't recognize it.  4/1 GB/FB RATIO !!!  His LD rate is up 3% to a normal 16% but his GB rate is up 17% to 72%. 

These two relief pitchers really can't prove anymore than they already have and guys like Josh Newman and Yabuta are taking up roster space in Omaha.  Heath Phillips could also be inline for a taxi cab out of town as he has been rocked the last few trips out.
Kila 5 of his last 9 with a double and 2 homers.  Brayan Pena is hitting .351 since being sent down and JR House and Ryan Shealy continue to hit well also.  Surprisingly Shealy has not hit a HR this season and is only sluggling .425 with a .345 BA.

While there isn't a whole lot of offensive help close to KC there could be bullpen help later in the season with guys like Nicoll, Hayes and Rosa.
