Marcum is the New Cutterballer

with 4 comments

How odd – after not throwing it at all his last few starts, Sean Marcum has leaned so heavily on his cut fastball while dominating Chicago for seven innings tonight that his pitch selection looked like the Jesse Litsch of old:

Marcum was effective tonight without the sinker or 4-seam fastball he usually throws, but he is throwing his curve again, and the cutter that put him on the DL in the first place. Gone are the days when he was throwing such an even assortment of pitches every start that he’s the sample of what a perfect pitch rainbow looks like – now he’s bringing a different selection every night.

As for location, Marcum painted the corner with his changeup diving down and away from righties, and threw his cutter in on the hands of left handed batters. Despite throwing 64.2% of his pitches for strikes, only 35.4% of them were in the zone.

  1. That looks like a really good cutter to me.

    Thanks for the analysis.

  2. I’m surprised that a cutter is so straight and yet isn’t crushed — is it’s effectiveness based on the fact that hitters are so accustomed to fastballs tailing away?

  4. “I’m surprised that a cutter is so straight and yet isn’t crushed”

    I think it’s more that the definition of 0 horizontal movement is a little misleading. Since all pitches tend to “move” away from a pitcher, if one cuts back in about a foot then the final “movement” value is at zero.

    Compared to a straight fastball though, it’s darting almost straight sideways half a foot and down but only a few miles an hour slower which I can only imagine would be really, really, annoying.

    Like, Wiffle annoying.
