Carter Kieboom is a first baseman for the Los Angeles Angels. In 2025 he hit 0 home runs and knocked in 1 RBI, notching 2 hits across 8 plate appearances in 3 games. His batting average was .250, 1.9% higher than the league average of .245. He reached base at a .250 clip and slugged .250, for an OPS of .500, 30.5% lower than the league mark of .719. He averaged 80.7 mph off the bat, hit 28.6% of balls in play at 95 mph or better and made contact on 80.0% of his swings. Adjusted for his ballpark and league, his 34 wRC+ puts his offence 66% below average. That comes to -0.1 dbWAR — -0.6 runs with the bat, -0.0 on the bases, -0.2 for the position he plays, against replacement level. It includes no fielding: defensive runs are proprietary and are not estimated here, so the figure credits playing a demanding position but not playing it well.

Head to head
Put Carter Kieboom beside up to three others.
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.
