Mike Yastrzemski is a left fielder for the Atlanta Braves. So far in 2026 he has hit 12 home runs and knocked in 41 RBIs, notching 81 hits across 400 plate appearances in 136 games. His batting average is .229, 6.2% lower than the league average of .244. He reached base at a .313 clip and slugged .387, for an OPS of .700, 2.6% lower than the league mark of .719 — 6th of 14 on his team, and 239th of 462 among MLB batters with 100+ plate appearances. He averaged 89.9 mph off the bat, hit 43.2% of balls in play at 95 mph or better, barrelled 5.0% of them and made contact on 76.8% of his swings. Adjusted for his ballpark and league, his 94 wRC+ puts his offence 6% below average. That comes to 0.7 dbWAR — -1.8 runs with the bat, -0.4 for the ballpark, -0.3 on the bases, +0.3 on double plays, -3.4 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.
