As spring training begins, a compelling ESPN analysis reveals that even the sport's best-prepared teams enter 2026 with glaring, unaddressed needs. The powerhouse Los Angeles Dodgers, who have assembled a historic roster, still lack a true ace pitcher—their "Holy Grail." This singular omission defines an otherwise flawless winter.

The Atlanta Braves face a prolonged crisis at shortstop, a weakness glaring against their otherwise elite roster. With Ha-Seong Kim injured, utility man Mauricio Dubon is an awkward temporary fix. Meanwhile, the New York Mets failed to re-sign closer Edwin Diaz after he accepted a better offer from the Dodgers, a potential playoff-series-defining gap.

The Seattle Mariners, despite a strong core, did not secure a second left-handed reliever, a critical vulnerability against heavy lefty-hitting lineups. These strategic gaps for contenders—and the varying philosophies behind them—set the stage for a season where championship aspirations may hinge on one unfulfilled offseason wish.
