Claimed off waivers, according to Hickey's P-I Blog.

I can't for the life of me figure out why the M's would put Chen on waivers.  Injury concerns?  Granted he's not exactly a star in waiting, but I thought the M's could use the depth in the middle infield.

Maybe this guy made him expendable? 

Hmmm.  Seems odd.  Very odd.  Probably the injury concerns, would be my guess...

(oh, and if the photos aren't big enough - you can actually make them bigger by clicking on them.  I didn't quite have 75 words to say about Chen, apparently, so I probably should let y'all know that).
