Joe Mack is a catcher for the Miami Marlins. In 2026 he hit 11 home runs and knocked in 34 RBIs, notching 49 hits across 229 plate appearances in 69 games. His batting average was .234, 3.8% lower than the league average of .244. He reached base at a .289 clip and slugged .426, for an OPS of .715, 0.6% lower than the league mark of .719 — 10th of 15 on his team, and 199th of 417 among MLB batters with 100+ plate appearances. He averaged 87.2 mph off the bat, hit 40.0% of balls in play at 95 mph or better and made contact on 74.9% of his swings. Adjusted for his ballpark and league, his 99 wRC+ puts his offence 1% below average. That comes to 1.1 dbWAR — -1.2 runs with the bat, -0.3 on the bases, +4.8 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.
