About this pitch Observed and derived
Bobby Witt Jr. strikes out swinging.
The pitch crossed the plate 4.19 feet high, above the batter’s tracked vertical zone (1.63–3.24 ft). It spun at 2,345 rpm. Over the whole flight MLB measured 15.7 inches of induced vertical break; the chart compares the last 50 feet only, so its figure is smaller.
Selection & sources
Five strikeouts from the day's finished games, chosen for variety from the 37 that had full tracking and an MLB clip: different pitch types first, then different pitchers, then speed. A sample, not a ranking. The notes are written from MLB's measurements, not by a person. Updates automatically from the previous Eastern calendar day, checked every 15 minutes while the site is in use. Only completed games with verified clips and tracking qualify; fewer than five pitches may be available. Retrieved 2026-09-14. The clip is the MLB broadcast; if it stalls.
Speed, spin and plate location are MLB’s tracking. The flight view is drawn from MLB’s fitted position, speed and acceleration at about 50 feet from home, ending at the front of the plate, and checked against the reported plate location. Measurements describe the pitch, not why the batter missed it. The chart is separate from the broadcast.
