    If the AFL was equivalent to the Midwest League (A) ball, Kris Bryant’s translational slash would be .295/.333/.579.

    Yes, please.

    MWL: .295/.333/.579
    FSL: .337/.381/.688
    SL: .357/.404/.742
    AFL: .422/.471/.933

    If you map out his small sample size along a 99% confidence interval and assume a normal distribution (a very shaky assumption, but close enough for already shaky MLE math), the theoretical lower bound for Bryant’s “true” talent level is a .233/.291/.837 slash (you can see why this is shaky, right?). That translates to the following MLB lines for each league talent level:

    MWL: .162/.196/.485
    FSL: .184/.226/.586
    SL: .195/.240/.637

    If the assumptions held true, you’d be able to say with reasonable confidence that Bryant would OPS, at the very worst, 681, at the major league level.

    The reason this assumption falls flat is because slugging percentage really doesn’t follow anything really resembling a normal distribution. It takes much longer for slugging percentage to normalize than OBP or BA. Still, kind of interesting. I’d say that the absolute lower bound for Bryant given his AFL performance is .190/.230/.360.

    @ Myles:
    So he’s better than Josh Vitters.

    …not exactly. If I say that Bryant’s absolute lower bound on his MLB performance is .190/.230/.360, I’m saying that’s his true talent level. He could theoretically hit .100/.120/.240 or so over some small number of PA and be compared to Vitters unfavorably.

    In fact, let’s look at Vitters’ MLB numbers and see what we come up with.

    Vitters had a hit 12.1% of the time over 99 trials. That means that the 99% confidence band is 8.46%, so his theoretical upper maximum is .206 (again, we are assuming that distributions are normal when they are not, ESPECIALLY among the extremes of performance).
    Vitters reached base 19.3% of the time over 109 trials. That means that the 99% confidence band is 9.75%, so his theoretical upper maximum is .291 (same caveat applies).
    The problem we run into with slugging is it’s no longer a simple trial that passes or fails. There are 4 types of success (single, double, triple, home run). If we broke them into their respective types (and combined them at the end), you’d perhaps get a more accurate number, but I think you’d get so much noise as to make the data unusable. To that end, I just use TB/AB. He had 20 in 99 trials for 20.2%. 99% confidence band is 10.41, so the theoretical upper limit is .306.

    tl;dr; Vitters true talent level last year could have been as high as .206/.291/.306. It’s reasonable (though the reasoning is quite shaky and relies on some rather dubious assumptions) to assume that yes, Bryant is a better hitter RIGHT NOW than Vitters is.
