What happened: Jacob Misiorowski threw the two fastest pitches in the pitch-tracking era to begin his postseason. The fastballs marked the highest velocities recorded since the measurement system was implemented in 2008.

Why it matters: The record-setting start establishes a new benchmark for pitching velocity in a high-stakes playoff environment. It underscores the overwhelming power he brings to the mound in October.

What to watch: Monitor his velocity retention and overall workload as the series progresses.
