Too few batters faced to grade
Seth Lonsway has faced 11 batters this season. A rate built on that few swings wildly on a single result, so this page shows no grade and no comparison to the league average or the league best — there is nothing here those numbers could honestly be put next to.
The bar is 40 batters faced, the same pool every league average and percentile on this site is measured over. What follows is what actually happened, with no grade attached to it.

How to read this chart
Dot color is estimated bases (EB) — what the contact was worth, regardless of what the defense did with it. So a dark hollow ring in the outfield is a crushed ball his defense ran down. Tap or hover a dot or a row to link the two, and use the ▶ links to watch a play on Baseball Savant.
