What happened: The cutoff is 250 ground balls in a single season across the last 10 seasons. Jean Segura is second at .326 from 2018, with Otto Lopez third at .319 in 2026.

Why it matters: Topping a decade-long ground-ball table reflects contact and speed turning grounders into hits. Having two 2026 seasons in the top three makes this year an outlier for that skill set.

What to watch: Simpson's contact form already shaped October with a go-ahead two-run triple earlier this postseason.
