Here are some known grade changes for hitters. As with the pitchers, this is a result of working on the 50/50 list where I slot players compared to others in different organizations.
UPDATED 4:40 PM MONDAY
Michael Saunders, OF, Seattle Mariners: Old grade was B-, he is being UPGRADED to Grade B because I want him to be a candidate for the Top 50. He ended up about the middle of the top 50.
Jeff Kobernus, 2B, Washington Nationals: Old grade was B-, he is being DOWNGRADED to Grade C+ because the first grade was simply a bit too aggressive and he fits better with the other C+s.
Josh Vitters, 3B, Chicago Cubs. Old grade was B+, he has been DOWNGRADED to Grade B. I knew I wanted him on the Top 50 and that he would be right next to Matt Dominguez. They both have flaws, they both have strengths, they are within one day of the same age, but ultimately I decided that I liked Dominguez slightly better because he'll stay at third base long-term and Vitters might not. If I had Dominguez as a B, Vitters couldn't be a B+, and I wasn't going to promote Dominguez. They are right next to each other on the Top 50.
