Looking at Joba Chamberlain’s slider

By

When Joba Chamberlain burst onto the scene in 2007, he did so with a hellish slider that got swings-and-misses more than half the time. That same slider has since regressed from outstanding to merely pretty good, still checking in at more than one run above average per 100 thrown in 2010. Lucas Apostoleris at Beyond The Box Score used some PitchFX Data to break down Joba’s slider, noting that not only did he throw it harder than ever before this season, but it also had less movement. Consequently, he left a lot more up in the strike zone, and spinning offspeed stuff that doesn’t break and is left up in the zone tends to get hit real hard. Check it out, there’s lots of neat and interesting graphs in there. Hopefully Larry Rothschild can get Joba figured out.

    I’d love to see Joba mix in his curve or change more. Unfortunately, those are “feel” pitches, and relievers don’t really have the luxury of building confidence in a pitch in the 8th inning of a close game.

    For his sake, I hope Joba gets traded. Him sitting in the bullpen is costing him millions.

      Him sitting in the bullpen is also costing the Yankees millions. Makes you wonder why they don’t just…

      • brockdc says:

        And here’s the thing: Even if the Yankees don’t see Joba as a top-of-the rotation starter going forward, they’d significantly bolster his trade value by putting him in the back end of the rotation now.

        • The Big City of Dreams says:

          Maybe they feel he can turn it around and be the replacement for Mo. The problem is if he has another inconsistent season than what do they expect to get from him in return.

      Agreed, if the Yankees aren’t going to give him a chance I’d prefer he could go somewhere where they would give him a shot.

      Vin Mazzaro got traded for a 2.5 WAR player. Surely Joba has some value in him.

    • Clay Bellinger says:

      Plus, no reliver wants to get beat on his 3rd or 4th best pitch. When you’re only facing a hitter once in the game you just go with your best.

      • vin says:

        Good point.

        If he can’t start, I’d love to see him used as a multi-inning reliever. Kind of like Mendoza or Aceves, but in higher leverage situations.

        I’m just dreaming though. Using him in any role outside of late inning reliever would be way too far outside the box at this point.

        • joe lefko says:

          The worst part is, after the Yanks got blasted for the way they handled him, even if he has a great ’11 in the pen (his peripherals are still very good, which i think people forget) and Andy retires, they still won’t give him a chance to earn a spot in 2012.

          • The Big City of Dreams says:

            That’s the thing they won’t even entertain the thought of putting him back into the rotation for 2012. I hope he gets traded but since the pen is thin I think the Yankees are going to try and “prove” that he can be a great reliever.

  2. It’s like he’s muscling it in out of frustration — overthrowing, aiming it in the zone. Sometimes less is more.

  3. All Star Carl says:

    He’ll turn him into Carlos Marmol. With less walks.

  4. Looking at Joba Chamberlain’s slider

    Takes 3-2 pitch out of the strike zone.

    Am I doing it right?

  5. Jon Kantrowitz says:

    Joba, Nova, Laird, 1 0r 2 more for Greinke?

    • whozat says:

      Montero, Gardner, Joba and Laird.

      • Stan the man says:

        That literally would be the dumbest trade in the history of the Yankees. Nothing like trading 2 top prospects and a valuable relief and a starting everyday MLB player for a pitcher coming off a bad season with social anxiety disorder to pitch big innings in NYC. That is literally a recipe for disaster.

  6. Dick Whitman says:

    Joba’s slider is like Hughes’ curve. Thrown harder, less movement, less effective.

  7. MikeD says:

    Maybe we should bring Guidry back this Spring for a little one-on-one work with Joba a nd his slider. Lyle taught Guidry his slider; Guidry taught Righetti; Rags taught Leiter. Joba’s slider was lights-out when Guidry was the pitching coach in ’07.
