Grade
His grade shows how good he has been, and at what.
Too few batters faced to grade
Welinton Herrera has faced 10 batters this season. A rate built on that few can swing a long way on a single result, so his rates get no grade and no league percentile yet.
A grade needs 40 batters faced. League medians and percentiles come from pitchers with at least 100 batters faced. The sections below show what actually happened, with no grade attached.

How to read this chart
Each row is a pitch he throws at least 3% of the time, from pitch tracking in the regular season. The bar is how often he throws it, then its average velocity and its whiff rate, the share of swings that miss. More whiffs are better for a pitcher, while usage and velocity describe how he pitches.

How to read this chart
Dot color is estimated bases (EB), what the contact was worth no matter what the defense did with it. Darker means more bases, 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.
