Grade

How good he's been, and at what

Too few batters faced to grade

Yilber Díaz has faced 28 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.

A grade needs 40 batters faced. League averages and percentiles are measured over pitchers with at least 100 batters faced. What follows is what actually happened, with no grade attached to it.

How the stuff has held up outing to outing

Contact allowed

What hitters do when they connect

Batters go to the pull side off him most often, but the hardest contact goes to the opposite field.

Pull and oppo are relative to each batter's stance, so this pools all the hitters he faced.

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.
