The Margin Ep. 5 | The Defense Tax

The Margin - Episode 5 - The Defense Tax  The Cubs have spent most of 2026 surviving a pitching staff that, statistically, looks mediocre. 39 pitchers used. One of baseball’s highest home run rates. A staff that entered the trade deadline near the bottom of MLB in pitching WAR. And yet the Cubs keep preventing runs. Why? Because behind every Cubs pitcher might be the best defense in baseball. Chicago leads MLB in Outs Above Average, Fielding Run Value and Defensive Runs Saved. They turn ground balls into outs better than anyone. They make fewer errors than anyone. And their pitching staff has produced the largest gap between ERA and FIP in baseball. So maybe we’ve been evaluating this pitching staff the wrong way. In Episode 5 of The Margin, Nate Ritchey examines The Defense Tax: how an historically elite Cubs defense changes the level of pitching Chicago actually needs to win. Because great defense doesn’t just make highlight plays. It gets the first out. It prevents the extra 90 feet. It kills rallies before they start. It turns crooked numbers into zeroes and ones. And if that’s intentional roster construction from Jed Hoyer, maybe the Cubs aren’t trying to build a dominant pitching staff. Maybe they’ve built a team designed to make an average one better. And in October, one out that another team doesn’t make might be the difference. The Margin — Chasing Wins, Not Stats. #ChicagoCubs #Cubs #MLB #TheMargin #Club120
