In Baseball America's 2007 Prospect Handbook, Jon Jay (Staunton 04) came in at #5 in the Cardinals' system. He fell to #11 in 2008, and then #12 in 2009. He did not make the top 10 for the 2010 list, either, but he was named in the Derek Goold chat (subscription only).
Jon Jay (My Computer): How far off the Top 10 did I fall this year, and how can I get back in your good graces?
Derrick Goold: Never fear, Jon Jay. You didn't fall that far, and while your start to the season was cause for concern the strong finish and a good turn in winter ball so far (.323/.418/.431) has buoyed your place in the rankings. A spot on the 40-man roster says it all. Follow Skip Schumaker's lead, save for that whole changing positions to second base thing.
Those numbers are what Jay still has in the Winter Liga Venezuela Beisbol Profesional.
Since ATVL helped with the Waynesboro Generals last year, he learned what can happen what a roster suddenly changes. For example, Matt Adams, from Slippery Rock, was recruited by Lawrence Nesselrodt to be the big batin the middle of the Generals' lineup. Adams, however, was drafted by the Cardinals, and turned pro instead. He went on to hit 355/400/547 in 245 at-bats at two levels. As a bonus, here is the question about Matt in Goold's chat:
Michael Stern (Rochester NY): Is Matt Adams considered a legit prospect? He had a great year with the bat in Rookie ball at 2 stops. Can he play anywhere else besides 1B? - because you might say he's blocked there if he wants to play in St. Louis.
Derrick Goold: You might say? Nah, you can go ahead and say it. Adams is a monster of a first baseman. The pride of Slipper Rock U led the nation in hitting this past season and fits the profile of the college player the Cardinals find under a Slippery Rock — excuse me, it had to be done — by sifting through and normalizing a cagillion stats from college baseball around the country. Adams can hit. But he's got to hit above rookie ball to move onto the prospect radar. It's too early in his career to start thinking that he's blocked in this organization. See what he does at a higher level this year and check back.
So, although Adams isn't technically a Valley League alum, I thought I would include some info on him here.
