Playing in all 162 regular season games is one of the rarest feats in modern Major League Baseball. When an MVP-caliber hitter plays every game, they generate ~680+ plate appearances rather than the ~540 PAs of an oft-rested star (130 G). That difference alone represents +140 PAs of elite +48% above-average run production.
In sabermetric WAR, positional adjustments equalize defensive difficulty per 162 games (DH: -17.5 runs, 1B: -12.5 runs, LF/RF: -7.5 runs). Moving from DH to 1B saves +5.0 runs of baseline adjustment per full season while unlocking the roster's ability to rotate another slugger into the DH role without sacrificing defensive innings.
Every missed game is not replaced by league average; it is absorbed by replacement level (0.0 WAR / ~75 wRC+). Over 30 missed games, this talent deficit costs roughly 15 to 20 team runs (approx. 2 full team wins in the standings), frequently deciding tight division and wild card races.
