The Late Show Specialists
Volta Redonda’s 1-1 draw with Avaí (June 17) extended their streak of matches decided after the 80th minute to four—a statistic that would give any analyst gray hairs.

Defensive Masterclass or Attacking Woes?
Three consecutive 1-0 results (Botafogo-SP vs Chapecoense, Paranaense vs Cuiabá) raised questions about tactical conservatism. My Python scripts detected a 17% drop in shots on target compared to the league average.

Key Data Points

• Set-Piece Supremacy: 42% of goals came from dead-ball situations (league average: 34%)
• Avaí’s Jekyll & Hyde Act: Conceded 4 to Atlético Mineiro but beat Cruzeiro 2-1 days later
• Promotion Race Heating Up: With Goiás winning two straight, our predictive model now gives them a 63% chance of top-four finish

Stat of the Round

Amazonas FC’s 2-1 win over Vila Nova saw them complete just 68 passes in the opposition half—the lowest by any winning team this season. Sometimes efficiency trumps possession.

Upcoming Fixtures to Watch

Our algorithm flags July 12’s Novorizontino vs América Mineiro clash as potential goal fest (predicted xG: 2.8). Meanwhile, railroad derby between Ferroviária and Brasil de Pelotas could be decided by which team’s aging midfield lasts 90 minutes.
