Early season: Teams have played fewer than 30 games. Probabilities are heavily influenced by prior expectations and will shift significantly as more games are played. The projected wins range reflects this uncertainty.

How BBMI simulates the season: Each remaining game is projected using Bayesian-shrunk team win rates that blend BBMI power rankings (60%) with prior-year Pythagorean records (40%), regressed 15% toward .500. Win probabilities use the log5 formula with a 54% home-field advantage. The simulation runs 10,000 Monte Carlo iterations — each iteration simulates every remaining regular-season game, then runs the full postseason bracket: Wild Card (best-of-3), Division Series (best-of-5), Championship Series (best-of-7), and World Series (best-of-7) with correct MLB home-field patterns. As the season progresses, observed records gradually replace priors (k=50 shrinkage). Results update each morning after the prior day's games are final.
