Brazilian Serie B Round 12: The Numbers Don’t Lie

League Context
Founded in 1971, Brazil’s second division has evolved into a 20-team proving ground for future stars. This season’s compressed schedule (thanks to Copa Sudamericana commitments) makes every point precious—especially for sides like surprise leaders CRB and traditional clubs like Vasco lurking just outside promotion spots.

Matchday Breakdown

  • Volta Redonda 1-1 Avaí (June 17): Avaí’s 86th-minute equalizer from a set-piece exposed Volta Redonda’s xGA (expected goals against) of 1.8—the league’s third-worst this round. My Python model flagged their zonal marking as statistically vulnerable last month.
  • Botafogo-SP 1-0 Chapecoense (June 20): A classic ‘smash-and-grab’ with Botafogo converting their only shot on target (0.07 xG). Chapecoense’s 72% possession yielded just 0.9 xG—proof that dominating the ball means little without penetration.
  • Amazonas FC 2-1 Vila Nova (June 22): The newly promoted side’s counterattacking masterclass generated 1.4 xG from just 38% possession. Their transitional play would make Atletico Madrid proud.

Trends to Watch

  • Set-piece kings: 43% of goals this round came from dead balls. Teams like Paraná Clube (who scored two headers) are exploiting weaker aerial defenses.
  • Promotion race: With 6 teams within 3 points of the top, my Monte Carlo simulations give Goiás (despite their inconsistent form) a 68% chance of promotion based on remaining fixture difficulty.

Up next? Keep an eye on July 7’s Railway vs Chapecoense clash—a relegation six-pointer where my model predicts under 1.5 goals based on both teams’ dire attacking metrics.
