Buster Posey, C, Giants: A simply outstanding '09 campaign (.325/18/80) earned him a cup of coffee with the big club in September. I'm interested to see if he or 2009 uber-prospect Matt Wieters has a better 2010 season line. Their skill sets are awfully similar.

Thomas Neal, OF, Giants: One of my personal favorites of '09, Neal bounced back from injuries to post a line of .337/22/90 in High-A. Facing better pitching will provide a better indicator if he is the real deal heading into 2010.
