Just so you know, word in Kansas City is that Carlos Beltran doesn't really have the arm he used to, due to elbow problems. I can't verify this or disprove it, but thought I'd offer it for what it's worth.
I went to my first Royals game of the season on Sunday, with 20-year old Zach Grinke not able to match Tom Glavine and--surpise, surprise--the Royals lost. Beltran badly misjudged the distance on a ball that turned out to be a home run, crashing painfully into the outfield wall; and this is in his home ballpark.
None of this means the M's shouldn't pursue him in the off-season, but he may not be quite the defensive juggernaut that some believe him to be.
If you don't read Sports and Bremertonians, then you missed their link to an article with Carlos Guillen's comments--which strike them and myself as pretty accurate--about the Mariner's foolish dismissal of Guillen's talent and potential.
