Nobody posted anything so far, so I thought I would, considering that these produce some of the best content on the site.  Notable pitchers today: Jon Niese, Shairon Martis, Adam Eaton, Sidney Ponson, Shawn Chacon, and Kris Benson (really? they still play?), Jeremy Papelbon, David Purcey, Kevin Pucetas, Daniel Hudson, Andrew Brackman, Jason Knapp, Stolmy Pimentel, and Ross Seaton.

However, easily, the top-prospect matchup of the day goes to:

Zachary McAllister against Tim Alderson at San Francisco's AA Connecticut.
