For now, he is staying. It will be interesting to see how the arbitration figures come out. The Pirates were shopping for a SS and both the Twins and Rays didn't want anyone but Joel, so those talks broke down. From what I have heard, the Rangers are hard after him so they can move Neftali to the starting rotation and just about everyone in the AL East wants him too. Personally, I would be surprised to see him still with the Pirates past the trade deadline this year.
Well Twins traded Hardy, too bad they couldn't work something out. I really like Joel as a pitcher and would like to see him on a winning team.
