Thanks for your comments. Regarding Joba Chamberlain, I think that his cards have still retained a good amount of their potential value throughout his time spent in the bullpen. In the past week or so, his 07 Bowman Chrome Auto RC has been selling in the $120-150 range, his Bowman Sterling Auto RC in the $70-80 range, and his in the Bowman's Best Auto RC $60-70 range. I don't know what these cards were selling for before (when he was starting), but these are all very high prices for a non-starting pitcher, meaning that collectors never believed that he wouldn't return to the rotation. When he does return, I think that his values could still increase if he does well, but if he doesn't meet expectations, his cards could potentially experience a bigger drop than we've seen thus far.
With the Yankees struggling so far in '08, Chamberlain could very well move back into the rotation very soon, and have the opportunity to shine (maybe he could take Phil Hughes' spot?). Honestly, Chamberlain isn't one of the players that I watch too closely, so all of this is just my semi-informed best guess.
Yes, I am a fan of Micah Owings (that obvious huh?) Did you see that he had a pinch hit 2-run homer tonight? He may put it all together this season. So far he's off to a well-balanced start, with a 4-0 record, 3.48 ERA & 8.13 K's/9IP pitching, and is batting .421 with 1 HR & 3 RBI in 19 AB. Not too bad!
