JaCoby Jones is a center fielder for the Detroit Tigers. In 2021 he hit 2 home runs and knocked in 9 RBIs, notching 17 hits across 105 plate appearances in 34 games. His batting average was .170, 30.3% lower than the league average of .244. He reached base at a .210 clip and slugged .250, for an OPS of .460, 36.9% lower than the league mark of .728 — the worst on his team, and 458th of 463 among MLB batters with 100+ plate appearances. He averaged 89.4 mph off the bat, hit 36.2% of balls in play at 95 mph or better, barrelled 8.6% of them and made contact on 63.0% of his swings. Adjusted for his ballpark and league, his 23 wRC+ puts his offence 77% below average. That comes to -0.7 dbWAR — -9.9 runs with the bat, -0.5 on the bases, +0.3 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.
