Wow Im just hearing of this trade. Im with you Pabs I thought Wilhelmsen could have played a big role out of the pen this season. lEonys Martin is great in the outfield, he can run well on the bases, but his bat leaves a lot to be desired. I imagine he'll be a regular at the bottom of the order.
Initial reaction is this is a move that benefits the M's. I think anytime you can get a starting OFer with a few years left on his deal for a reliever, it's a win.
Dont know much about the reliever thats coming in with Martin, and a change of scenery just might be what james jones needs. Put him in the minors and let him work with coaches who can help develop his bat a bit.
