Jon Heyman has a list of his Top 45 trade prospects posted today. http://www.cbssports.com/mlb/story/1...-with-pitching

6. Morneau (although Heyman says he still isn't playing the field -- I guess I've been seeing a mirage out there)
Possibilities of trading most of these have been mentioned in other threads. No mention of Span.
