Jonah Cox is a center fielder for the San Francisco Giants. So far in 2026 he has hit 4 home runs and knocked in 16 RBIs, notching 37 hits across 161 plate appearances in 54 games. His batting average is .259, 6.1% higher than the league average of .244. He reached base at a .307 clip and slugged .392, for an OPS of .699, 2.7% lower than the league mark of .719 — 9th of 18 on his team, and 241st of 462 among MLB batters with 100+ plate appearances. He averaged 79.6 mph off the bat, hit 36.4% of balls in play at 95 mph or better, barrelled 5.7% of them and made contact on 62.3% of his swings. Adjusted for his ballpark and league, his 96 wRC+ puts his offence 4% below average. That comes to 0.7 dbWAR — -1.1 runs with the bat, +0.2 for the ballpark, +1.1 on the bases, +0.2 on double plays, +1.2 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.
