Each square is a spot the pitch crossed; the dark box is the strike zone. Orange = he hits it, blue = he misses or makes an out there. The number is how many pitches he's seen there, so one or two doesn't pass for a trend.
Hot: middle, belt-high. Cold: low and in. Chases low and away (swung at 4 of 6).
Work on: let the changeup go by, sit on the fastball.
vs #22: 2 for 5. Hits his fastball; sit on it.
Same card, from our pitchers' charting. Opposing kids are a team and a jersey number only, never a name.
Got him out: fastball up and in (3 of 4). Don't: changeup middle, 2 hits.
Ethan got him twice. Note from last game: "Bunts with a runner on 1st."
