Possible successor and heir to Josh Beckett.
Any reasonable price should be paid.
The Mariners wouldn't be as interested in Buchholz because what they want is 6 years of cost control on a high ceiling guy. And they're desperate for a decent 1B. Kelly and Anderson would be a good starting point from Seattle's perspective, I'm thinking. They'll want more, but those two will get you in the door. And I wouldn't worry about trading either of them because our core rotation would be young and excellent with Beckett, Hernandez, Lester, Daisuke, and Buchholz, and good pitching prospects come along with fair regularity, and if we lose Anderson, Youks still has a few good years and Rizzo's not that far behind.
