This is a bit of lab work, but here’s a new graph/chart I’ve been tinkering with. It’s each of Lincecum’s strikeouts by pitch-type from yesterday’s 12 strikeout masterpiece. Each strikeout is color coded for pitch-type (red = fastball, green = slider, yellow = changeup, blue = curveball). I’ve included if the pitch was a swinging strikeout (as depicted by the black outline) or if it was a foultip strikeout (the dashed outline), or if it was a called strike three (no outlines of any sort). The inning is labeled on the vertical axis.
Hopefully, you can quickly look at the image and see how Lincecum struck out batters in the game. I thought it was interesting that Lincecum really leaned on his slider as his strikeout pitch over the last few innings; five of his final eight strikeouts were by the slide piece. Lincecum’s 12 strikeouts break down as follows: (6) sliders, (3) fastballs, (2) changeups, and (1) curveball. And all strikeouts were swinging, no called strikeouts today.
As usual, feedback is welcomed. I’d love to hear what works and what doesn’t work.
