Mike Yastrzemski is a left fielder for the Atlanta Braves. In 2026 he hit 8 home runs and knocked in 33 RBIs, notching 61 hits across 300 plate appearances in 100 games. His batting average was .230, 5.5% lower than the league average of .244. He reached base at a .313 clip and slugged .385, for an OPS of .698, 2.9% lower than the league mark of .719 — 8th of 12 on his team, and 224th of 417 among MLB batters with 100+ plate appearances. He averaged 90.0 mph off the bat, hit 44.3% of balls in play at 95 mph or better, barrelled 6.2% of them and made contact on 76.4% of his swings. Adjusted for his ballpark and league, his 95 wRC+ puts his offence 5% below average. That comes to 0.4 dbWAR — -1.5 runs with the bat, -0.2 on the bases, -3.9 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.
