Exploiting wRC+ Splits in 2026

With a third of the season in the books, the sample size for certain data and metrics has grown from too small to large enough that it must be taken seriously. The New York Yankees post a wRC+ of 123 against left-handed pitching — the best mark in baseball. The Mariners, another pre-season World Series contender, sit at 75. That 48-point gap between the two elite lineups on paper, against southpaws, is no longer such a small sample that we need to ignore it. Leveraging platoons has long been an important strategic lever for lineups looking to gain an advantage. Using wRC+ through the first stretch of the 2026 season, we can see every team’s offensive production against left- and right-handed pitching to find where the real discrepancies lie, and how we can target these matchups on both sides of the ball as we move deeper into the season, and what trends we should be watching.
