Matt Mervis is a first baseman for the Miami Marlins. In 2025 he hit 7 home runs and knocked in 14 RBIs, notching 21 hits across 134 plate appearances in 42 games. His batting average was .175, 28.6% lower than the league average of .245. He reached base at a .254 clip and slugged .383, for an OPS of .637, 11.4% lower than the league mark of .719 — 15th of 17 on his team, and 328th of 461 among MLB batters with 100+ plate appearances. He averaged 88.3 mph off the bat, hit 38.0% of balls in play at 95 mph or better, barrelled 8.5% of them and made contact on 60.1% of his swings. Adjusted for his ballpark and league, his 75 wRC+ puts his offence 25% below average. That comes to -0.3 dbWAR — -4.4 runs with the bat, -0.1 on the bases, -3.2 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.
