Mark Lowe not a starter?

Last night during the post game radio show, a caller asked why Mark Lowe is not being considered for the starting rotation.

Shannon Drayer took the call, and in a sniveling tone (I think she has a cold) stated the Mariners have already determined Lowe is not an option for the rotation. When the caller in a roundabout way said his stuff is too good not to be considered, Shannon dropped more information I've never heard.

According to Drayer, the M's have a concern with Lowe's mechanics and feel he is at risk for injury if he moved to the starting rotation. So for now at least, Lowe is going nowhere. I should point out that Drayer then went on a bit of a rant, and argued that M's fans are stupid for complaing when Mariner pitchers always get hurt, and then complain when they hold them back.

When the caller pointed out Lowe has better stuff than Pineiro, Drayer went into some crazy outburst, blabbering on about Pineiro's six years experience as a starter and how it was crazy to claim Lowe was better. But I digress...

Has anyone heard about the Mariners shutting down Lowe as a starter? Anyone heard why he is at risk of injury (according to the Mariners)?

I hope this is only for this season, as I would like to see Lowe considered for the rotation next spring. It will be something to keep an eye on...
