Lost: the Velocity and Command of Joba Chamberlain

I was asked by a few people to diagnose the problems of Joba Chamberlain. I
went to the tape and didn’t really see anything that looked like an obvious
problem.

Joba’s problems persisted and I saw a Buster Olney blog entry detailing Joba
’s velocity decline (Insider-only), so I decided to take another look and I
think might have found something.

I’ll also be ignoring the yo-yo act the Yankees have used with Joba. Should
he be in the rotation or should he be put in the pen? To use Joba rules or
not? I’m sure he’s been mentally all over the place and that’s had
something to do with his performance, but for this piece, we’ll ignore that
factor.

Now, let’s compare Joba from September this year to Joba back in the middle
of last season…

2008 Joba is on the left, 2009 Joba is on the right. First thing I notice are
the hands…as Joba lifts his knee, the hands in 2009 lift with it while in
2008 they stay steady. That’s why in 2009, at the point the knee starts to
drop, Joba’s hands are up by his head and in 2008 they are out in front of
his chest. So right off the bat, we see a subtle change that might have an
impact on his timing.

Joba actually breaks his hands (when the ball breaks from the glove) a couple
frames earlier in 2008 than 2009. In 2009, Joba lowers the hands and then
breaks.

In 2008, Joba broke his hands and then they kinda hover there. This is
something I detailed last time I looked at Chamberlain. It’s an adjustment I
think he made in hopes of improving his timing, which in turn would help his
command. The hands hovered as Joba started striding.

In 2009, the hands also hover, but they don’t hover for as long a period.
The reason for this is because his hands are higher from the start, so the
time it took for them to lower ate into the time that his hands were supposed
to hover. Hopefully that make sense.

Now, there are postural, hip turn, and arm action difference. Here are some
of those changes…

1. Chamberlain in 2008 is a bit more seated.

2. Take the clip below and watch the front leg…

It looks like there is a bigger, more forceful step over move in 2008. That
is something that could make an impact from a velocity standpoint.

In fact, just comparing his pitches from his last start, when he would throw
in the upper 80’s – low 90’s, there was less of step-over move than when
he threw 93 or 94.

3. For the clips below, focus on the arm action…

In the 2008 version, as Joba is making that step-over move, watch the arm
action really start to load. The elbow goes up with a little bend.

Compare it to 2009…the arm swings back a bit, but it’s still pretty
straight and it hasn’t really begun to load. So Joba loads his arm later in
the process and this creates a timing problem.

Now, I think a pitcher’s “timing” is subjective. Some regard a problem in
timing as just the throwing arm not being vertical prior to the front foot
landing. That’s not really true, however.

I’ll keep try to keep this simple because there are a lot of variables here…
despite the fact that Joba has always been borderline as to whether he gets
the arm up to vertical before the front foot lands, he’s been able to
generate pitches of high velocities and command them for the most part. When
you’re able to combine high velocities with command, it’s a sign of
mechanical efficiency, not a problem in timing. Proper timing for one pitcher
may not be proper timing for another.

But what happens when something is altered in a mechanically efficient
pitcher? It’s what you’d expect…you see a decline in velocity and a
deterioration of command…in Joba’s case, the arm is later in 2009. The
timing of each sequence in the kinetic chain is thrown off.

So what advice do I have for Joba? It’s pretty simple…go back to what made
you successful. Sit down a little more, keep your hands low, aggressively
step-over into foot plant, and the timing should correct itself. The changes
themselves won’t be too hard to implement, but Joba has to know what’s
wrong first.
