MLB Offseason Report Cards: Which Rosters Gained the Most Betting Value for 2026?

By Oddixa — 2026-02-18

As Spring Training begins, we evaluate how every MLB front office performed this winter and identify which teams have shifted their championship odds.

With Spring Training camps officially open, the dust has settled on a frantic 2026 offseason. Our final report cards for all 30 franchises are in, grading every major acquisition, trade, and departure. While some front offices successfully plugged holes in their rotations, others left fans—and bettors—wanting more. For those looking at the futures market, these grades serve as a vital blueprint for identifying which teams are undervalued heading into the marathon 162-game grind.

From a betting perspective, the 'A' students are the ones who bolstered their depth to survive the inevitable injury waves. Teams that landed elite top-of-the-rotation starters have seen their World Series odds sharpen significantly, while the clubs that failed to address bullpen volatility could be 'fade' candidates in early-season late-inning scenarios. As you look at the updated win totals at the sportsbooks, compare them against our grades to see where the market might be overreacting to big-name signings versus actual roster improvement.
