Head to head · 2024 batting

Heston Kjerstad vs J.D. Martinez

In 2024 the two have been worth the same 0.4 wins. Both lines are computed from play-by-play on the same constants, so they are measured the same way rather than quoted from two sources.

2024 batting. The stronger figure in each row is highlighted — for strikeout rate that is the lower one.

Career

Totalled over the seasons published here, which is not the same as a whole career: a player who debuted before 2015 begins at 2015, not at his real first game.

Career batting totals. AVG and SLG are recomputed from the components rather than averaged; OBP, wOBA and wRC+ need each season’s own constants and are left to the table above.

More head to heads

The same seasons, measured against somebody else.

How these are computed

wOBA uses linear weights measured from this season’s own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page. To put these two beside a third, the comparison page takes up to four.
