Prospect grade update

Jeri and I are working on editing the 2014 Baseball Prospect Book. The .pdf version will be emailed to everyone who orders the book, either the .pdf version or the paper copy, as soon as the editing process is complete. Part of the editing process involves reviewing each grade for each player. These get changed sometimes, so here is the current list of grade changes.

Early versions of each grade were posted in the Baseball Organization Top 20 Prospects Lists that were completed last week. These grades supersede the grades in those articles. The articles will be updated to reflect the changes in the coming days.

KNOWN GRADE CHANGES
Jason Adam, RHP, Royals: change from Grade B- to Grade C+
Jesus Aguilar, 1B, Indians: change from Grade C to Grade C+
Mark Appel, RHP, Astros: change from Grade A- to Grade B+

A.J. Cole, RHP, Nationals: change from Grade B to Grade B+
Jon Denney, C, Red Sox: change from Grade C+ to Grade C
Joey Gallo, 1B, Rangers: change from Grade B- to Grade B

Sean Manaea, LHP, Royals: change from Grade B to Grade B+
Trey Mancini, 1B, Orioles: change from Grade C+ to Grade C
Deven Marrero, SS, Red Sox: change from Grade C+ to Grade B-

Gregory Polanco, OF, Pirates: change from Grade A- to Grade A
Michael Ratterree, OF, Brewers: change from Grade C+ to Grade C
Alex Reyes, RHP, Cardinals: change from Grade B+ to Grade B

Taylor Rogers, LHP, Twins: change from Grade C+ to Grade C
Miguel Sano, 3B, Twins: change from Grade A to Grade A-
Jimmie Sherfy, RHP, Diamondbacks: change from Grade C to Grade C+

Jon Singleton, 1B, Astros: change from Grade B to Grade B+
Jameson Taillon, RHP, Pirates: change from Grade B+ to Grade B
Yordano Ventura, RHP, Royals: change from Grade B+ to Grade A-
Taijuan Walker, RHP, Mariners: change from Grade A to Grade A-


Some of these grades (Taillon, Sano, Walker) have changed due to player injury, others due to spring training and early-season information. A few changed because of projected slotting on the Top 100 Prospects list. For example, I want Joey Gallo on the Top 100 but he wouldn't qualify with a B-, so for proper slotting his grade needed to move up.

I will answer any questions you have in the comments section.
