Question 1

What does the H2H signal mean?

Accepted Answer

The H2H signal uses Bayesian shrinkage to determine whether a batter-vs-pitcher matchup has enough plate appearances to be meaningful. Noise means fewer than 5 PA, Weak means 5-14 PA, and Strong means 15+ PA with a reliable OPS sample.

Question 2

How is the zone heatmap calculated?

Accepted Answer

Zone heatmaps show batting average by strike zone location for a specific batter against a specific pitcher. Red zones indicate areas where the batter hits well, blue zones indicate pitcher dominance. Requires sufficient PA for meaningful data.

Question 3

Accepted Answer

Yes — HeatCheck HQ offers free MLB batter vs pitcher matchup lookups for every game. Search any batter-pitcher pairing by name, view career H2H stats, and see zone heatmaps at no cost.

Question 4

Accepted Answer

HeatCheck HQ provides free daily MLB batter vs pitcher stats including career AVG, OPS, HR, and extra-base hits for every matchup. Select today's games or search any player by name.

Question 5

How many at-bats do you need for meaningful BvP data?

Accepted Answer

Generally 15+ plate appearances give a statistically meaningful sample. HeatCheck uses Bayesian shrinkage to weight small samples toward league average, so even 5-10 PA matchups show adjusted estimates rather than noisy raw numbers.

Question 6

What is a BvP matchup in baseball?

Accepted Answer

BvP (batter vs pitcher) matchups show how a specific hitter has performed against a specific pitcher across their careers. Key stats include batting average, OPS, home runs, and strikeout rate in head-to-head at-bats.

Question 7

How do I use batter vs pitcher data for MLB props?

Accepted Answer

Look for batters with strong career numbers against today's opposing pitcher — high AVG, OPS above .800, or multiple HR. Combine BvP data with recent form, platoon splits, and park factors for the most informed prop bets.
