  1. Nice analysis and something to think about, but I wonder about one thing. There are a few guys on here — Mortensen and Guerrier are the clearest — who throw “hard” sliders that are less than 4 mph off their fastballs. Given that the most proficient practitioner of a cutter here (Marshall) throws one that’s farther off the two-seamer than that, and that the movement of a cutter seems to have much in common with a slider (unless I’m misreading both f/x and my view of the pitches at the park), might the designations need a little fine tuning? Not that that’s likely to change the conclusions of the article, and I realize that there are (usually) difference in the mechanics, but I’ve always wondered about the pedigree of these sorta-off-speed pitches and this might be a time to delve into that.

  2. Romo is amazing, the hitters know the slider is coming most of the time and still can’t hit it.

  3. This is a great point actually. We could sort by least FB+CT+SL… Cory Burns would probably still be number one but we might get some other names. And they might stay healthier longer. But they’d probably have a hard time without a pitch that even approached 90… right??

  5. I’m reminded of Doug Jones.
    He had a pretty good run throwing 80mph “fastballs” and 60 mph “changeups”: 303 saves in 846 appearances over 16 years.

  6. “Being slider-heavy also makes you prone to the platoon splits commensurate with the pitch…”

    Not in Romo’s case though. For his career RHB have hit .189/.235/.310 (.545 ops) against him while LHB have hit .188/.252/.278 (.530 ops) against.

  7. That would be a great retort if anyone was comparing Romo to Mo.

  8. Interesting analysis….saw Storey pitch for OKC against Reno last May, and the contrast was startling – he dominated when throwing breaking balls, but got raked whenever he tried to sneak a fastball by….doubt he would have sniffed the bigs with any team other than than Astros, However, it was good to see a guy without the big heater have a little success, and I could see him as a long relief type on a deep staff.

    Also saw Burns pitch on TV last last year, but didn’t see him show the same sharpness with his breaking balls as Storey…..but like Storey, some teams still see some value.
