    The MLB rule is that a pitcher has to declare their handedness from which they throw in the age old ambidextrous pitcher vs the switch hitter. Also the rule is that a pitcher must face at least one batter outside of an injury occurring.

    Are there any obligations for a team to use their starter more than one batter to kill lineup stacking.

    I understand there are some preventative measures naturally with having to have a couple long relievers of each handedness always ready to go and burning an initial bullpen arm but I could see this as an effective strategy that’s going to continue to push the envelope in new ways. Could the starter method be killed off altogether for having your best pitcher going everyday? It will be interesting to see how the baseball purists try to institute rules to prevent it (maybe extend a starter to pitch at least a set amount of innings?)

    If good pitchers were a dime a dozen this may work. But that’s far from the case.

    plus you loose far more from your very good (and plus) starters. while the l/r splits are important, they matter far more for your league average arms that make up the bulk of bullpens than they do for real front of the rotation guys. think how much edge a team would loose from doing this with mad max or degrom.

    i think the more likely adaption continues down the sp = five innings/2 times through road.

    Chew on this:

    2017 End of Season Pitching Stats per ESPN:

    ________ERA BAA WHIP K/BB K/9
    Starters:_ 4.49 .261 1.36 2.58 7.94
    Relievers: 4.15 .245 1.32 2.58 8.97

    With a full season of data, relievers are outperforming starters in almost every statistic.

    To compound the differential consider the weighted average sample size between a teams top 2 starters (360 IP) vs Setup and Closer (120 IP) and you can deduct that the middle relievers are beating the pants off the 3-4-5 starters. The gap is similar if not further in favor of relievers throughout the past few years.

    i see numbers there that can be accounted for by BABIP and other short term/noise data points. for example, there is a difference of 26,787 IP for starters to 16,469 for relievers

    Surely this is sarcasm?

    The problem with this is that many relievers are specialists and only face batters they have a significant advantage on so we should expect their numbers to be favorable. Starting pitchers do not have that luxury.
