One thing the sabermetric revolution has taught us is that batting order doesn't matter all that much. At least, not in the traditional sense of putting a speedy runner at the the top, someone who can handle the bat and move him over second, and power hitters in the middle. The general consensus now is that a team's best hitter should hit second with a high-OBP hitter in front of him.
The Blue Jays used Nathan Lukes in the two-hole for much of 2025, and that strategy worked well until the World Series, where his OPS sank to .457 against the Dodgers' elite pitching staff. Would that exceptionally tight series have unfolded differently had Guerrero been up instead in a few of those crucial spots? George Springer will presumably bat leadoff again for the Blue Jays in 2026, especially if Bo Bichette doesn't return this winter.
