Just a few links to tide you over this Saturday afternoon.
Tim Marchman lays out the facts about Derek Jeter. As usual, Marchman hits on the most important points. The takeaway:
You can futz with the math a bit, but even after you apply a standard aging curve, even after you weight 2010 more heavily than 2009 and 2009 more heavily than 2008 and do all other good things backed by actual research rather than one’s vague sense that the man’s bat has slowed and that time has crept upon his face, he projects as a very good player for next year and even beyond, one whose declining offense is offset by his ability to play a lot, to run the bases well, to field a difficult position tolerably and so on.
Beyond the Boxscore takes a look at Joba Chamberlain using PitchFX. It’s a neat look at how things have changed, but I’m not sure how much the article itself helps — the author fails to take into account Joba’s shoulder injury from 2008. That seems particularly important when evaluating his progression as a pitcher.
