Moving On Up?

With June just around the corner, I am curious to see if any minor league players are promoted to the next level for the second half of the season.

A few possibilities:

Bud Norris, RHP, Round Rock.  Norris has 2.72 ERA in eight starts.  He is not on the 40-man roster, but I wonder if he would get a look for a start or two if Hampton has another encounter with a bar of soap.

Polin Trinidad, LHP, Corpus Christi.  Trinidad just threw a complete game for Corpus and has a 3.34 ERA in 35 innings.  He was called up to Corpus Christi at the 2008 mid-point.  Other than Norris, Round Rock doesn't have any starters to block Trinida's progression.

Jason Castro, C, Lancaster.  Castro is .267 with five home runs and 27 RBI so far in California.  I will be interested to see how aggressive the Astros are with him.

Bryan Hallberg, RHP, Lancaster.  Hallberg spent all of last season at High A Salem with a 2.68 ERA.  So far this season, he has a 3.08 ERA in 26 1/3 IP out of the bullpen.  He may be following Chia-jen Lo and Daniel Meszaros to Whataburger Field.

Robert Bono, Kyle Greenwalt, and Ross Seaton, RHP, Lexington.  These three have been steady so far.  Plus, Ed Wade made some comments on KTRH about Lexington pitchers moving up soon.
