Tyler Glasnow is 99th percentile in extension at 7.5 feet 📊 The 11-season veteran joins #MLBTonight to talk about what Via @MLBNetwork on X

What happened: The 11-season veteran joined MLB Tonight to discuss how his mechanics have evolved over his career.

Why it matters: The discussion came days after his Aug. 25 return from the 60-day injured list. His release point shortens hitters’ reaction time, shaping how his mid-90s fastballs play.

By the numbers: His 2026 four-seamer has averaged 95.3 mph, while his sinker has averaged 95.7 mph. Hitters have batted .297 against the four-seamer and .097 against the sinker.

What to watch: His next outing will show whether the 7.5-foot release holds as he rebuilds his workload.
