Pineda back on the bump tomorrow. I expect the Yanks to probably be a solid favorite against the White Sox, especially with Miguel Gonzalez opposing. Found a decent article on the "enigma" that is Pineda that reminded me of this thread. Not a lot of answers provided to his future performance (obviously, as that would be the greatest article ever), but gives an idea why some really like him, which I believe also includes the linesmakers. (Last portion of the article is on Pineda.)
