Here are some grade changes for significant prospects.

Dan Hudson: changing from Grade B to Grade B+:  He was right on the edge but after looking at the numbers, video, and scouting reports again, I'm moving him up a notch to Grade B+.

Brian Matusz: changing from Grade A- to Grade A:  He's about a safe a pitching prospect as you can find, and I'm convinced by the arguments of Orioles fans that he deserves the A.

Mike Moustakas: changing from Grade B+ to Grade B: I've been planning on this change for awhile after seeing him in the Arizona Fall League. I still think he could have a strong breakout in 2010, but I didn't like the way his body looked in Arizona...he looks stockier and less athletic than a year ago.

These grades will be updated on the team lists.
