Grade

His grade shows how good he has been, and at what.

Too few batters faced to grade

Yilber Díaz has faced 34 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.

He rarely throws his knuckle curve (3% of his pitches).

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. The Bases vs average bars score each pitch against a league-average pitch in the same count, and a bar to the left (saved) is better.

How to read this chart
Each row shows how often he throws a pitch to left-handed hitters (LHH) and right-handed hitters (RHH). A mix is a plan, so a higher or lower share is neither better nor worse.

By appearance

These charts follow his velocity, movement and pitch mix one outing at a time, and each pitch keeps the same color in every chart. The velocity and movement charts also shade the middle of the league for scale.

Contact allowed

These cards show what hitters do when they make contact.

Batters go to the pull side off him most often, but they do the most damage to the opposite field.

Pull side and opposite field depend on which side each batter hits from, so this pools every hitter he faced.

Luck check

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.
