Peter Lambert is a starting pitcher for the Houston Astros. In 2026 he struck out 153 batters over 153.2 innings across 28 appearances, 28 of them starts, going 8-10. His ERA of 3.87 is 7.5% lower than the league average of 4.18 — 7th of 20 on his team, and 237th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 3.94 FIP suggests the ERA was no fluke. He missed bats on 25.5% of swings (12.4% of every pitch he threw), walked 9.0% of the batters he faced and struck out 23.3%. His 2.2 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.

Peter Lambert's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
