SI.com’s Jon Heyman was a guest today on WFAN’s Mike and the Mad Dog program. Heyman had some really interesting things to say about Aaron Heilman…

“There are guys in the organization that are worried about the way he is reacting to NY. I know, he has been here for a few years but this is the first time that he is getting a real taste of the booing. They are wondering if he is a sensitive guy.”

“He’s very talented and teams are trying to “bottom Fish” for him now. I know Arizona is interested and Colorado. I’m sure half the league is interested. They may think they can get him at 50 cents on the dollar. But the Mets have said, “No we want him on our team”.

“There are other teams that see him as a starter. The Mets do not see him as a starter. He’s a two pitch pitcher plus with his mechanics, he has what they call a “high back elbow”. He moves his elbow way back and it’s not real conducive to a breaking pitch. They think with that form, if he throws more than a 100 innings he will put himself in jeopardy for an injury. They site Mark Prior, who is a guy with a similar style. He threw over a 100 innings and was injured right away. So, they are being safe. They want to keep him as a relief pitcher. Also, there is the fact that he does not have a great breaking pitch.”

Heyman did a great job explaining the mechanics of Aaron Heilman’s pitching style and why the Mets won’t use him as a starter. The Mets tried to change Heilman’s delivery in the past but he was not comfortable or effective with the adjustments. I think I actually see what Heyman is talking about in the picture up top… Interesting stuff.

Ken Rosenthal of Foxsports.com is reporting that P Mark Prior has agreed to a 1 year deal with the San Diego Padres.
