It matters, and quite a bit. Left-handed hitters have small edges: they stand a step closer to first base and tend to see the ball better from right-handed pitchers, who are the majority. That’s why a hitter’s «side» is part of the strategy.
The matchup game
The general rule is that a hitter fares better against a pitcher of the opposite hand: a lefty hits righties better, and vice versa. Managers exploit that constantly, bringing in left-handed relievers to face left-handed hitters in key spots.
The solution: switch-hitting
Some players are switch hitters: they bat from both sides depending on the pitcher, so they always hold the edge. Greats like Mickey Mantle built their careers on that skill.
