Arsenal Analysis: Dodgers Worst Pitches Of 2012 – Relievers


As fans of the Dodgers, we’re always analyzing which pitchers have the best and worst pitches, but we normally base that on nothing but our own feelings at the moment, so I decided to take a more objective look at things.

For a pitch to qualify for these rankings, I used a 200-pitch minimum for starters and a 50-pitch minimum for relievers. The metric used to measure pitch effectiveness is True Average (TAv), which is basically like wOBA. League average performance is set at .260, and the metric doesn’t include baserunning.

Additionally, to prevent the post from being solely numbers-based, and one that would have been mind-numbingly boring, I decided to provide visual evidence as well.


Worst Overall Pitches

Shawn Tolleson – Sinker – .395 TAv


Mike MacDougal – Sinker – .342 TAv


Matt Guerrier – Fastball – .320 TAv


Relief pitchers have smaller sample sizes, so they are prone to fluctuations, but they have the advantage of appearing in short bursts and limiting their arsenal to only their best pitches.

So … uh … this is TERRIBLE.

.395 is like 40 points higher than Mike Trout in 2012 for fucks sake.

No … just no.


Jamey Wright – .258 TAv


Scott Elbert – .242
Javy Guerra – .208
Kenley Jansen – .187
Matt Guerrier – .139


Javy Guerra – .271 TAv


Jamey Wright – .171

Finishing last out of two isn’t bad, but giving up a .271 on a curve as a reliever is.


Kenley Jansen – .236 TAv


Jamey Wright – .215
Todd Coffey – .214
Shawn Tolleson – .206
Brandon League – .147
Ronald Belisario – .121
Randy Choate – .058

I actually think he could benefit from throwing this more often because it’s a quality pitch. Not hanging it is a different story, but how is he supposed to learn command of it if he never uses it?


None Qualified


Brandon League – .096 TAv

He’s the only reliever that qualified for this pitch, so I guess he’s technically the best and the worst, but considering his split was the second-most effective pitch by a reliever for the team in 2012, I’m pretty sure he gets a pass.
