Velocity Charts

» 12 April 2009 » In npb, pitching »

I’m working on a way to gather pitching information for NPB games. It’s not quite Pitch F/X but it should yield some interesting information. I’m not done yet, but the early results are good. I was able to chart the velocity on each pitch thrown by Hisashi Iwakuma and Hideaki Wakui in their April 10 matchup, which Wakui won 6-0.

Iwakuma was lifted after six innings and 92 pitches, allowing three runs. 

wakui_velocity

Wakui used seven different pitches, though he only threw his changeup a couple of times. He threw 138 pitches, and note that his fastball’s velocity drops toward the end.

    Interesting. Bit of clustering on Wakui’s pitching. Can you do Darvish next? Sorry, I’m a Fighter’s fan.

    I’ll have Darvish after his next start. Hopefully by then I’ll be able to post some cooler stuff as well.

    Thanks! And keep up the good work. I live in Sapporo, and love baseball. I speak, but can’t read, Japanese. I check your site every morning. Wish there were more English sites. By the way, you planning to post box-scores someday? It’s the thing I miss most- being able to see how the other games went. I watch all the Fighters games on T.V., but would like to see more stats on the other games. Don’t get enough from a 50 word game summary, and the T.V. news coverage is Fighters and Giants only in Sapporo. As if you aren’t busy enough already…..

    Shaggy, go to this website for Box Scores: http://www.npb.or.jp/eng/

    It’s the English language version of the NPB’s official site.
