Team Analysis

Miami Marlins

The Marlins enter this contest at 1-4 over their last five games, but their 5.4 RPG over that span points to an offense capable of producing at a winning level. Kyle Stowers’ power numbers continue to stretch opposing pitching, while Xavier Edwards’ contact skills keep innings alive and create RBI chances. On the road, their 30-32 mark shows they can compete away from home, especially when their lineup strings together extra-base hits against teams with strong home records.

Agustin Ramirez adds another run-producing threat, giving Miami multiple avenues to pressure Boston’s staff early. Despite recent losses, the Marlins’ offensive metrics point to a team that can leverage timely hitting into high-scoring outputs, especially against a Boston side that has shown defensive vulnerability in recent outings. With their ability to score in bunches, Miami is positioned to turn run production into an outright win.

  • WHIP: 1.3

Away Record: 30-32 • Home Record: 28-31
Last 5 Games: 1-4 (5.4 RPG)
Last 10 Games: 3-7 (4.8 RPG)


Boston Red Sox

The Red Sox’s 1-4 mark in their last five games mirrors Miami Marlins’ recent record, though their 5.4 RPG over that stretch reflects continued offensive output. Trevor Story’s run production remains a central factor, while Alex Bregman’s on-base consistency creates scoring chances. At home, their 39-22 record shows they typically convert Fenway’s dimensions into offensive advantage, but recent inconsistency in converting those opportunities into wins has narrowed their margin for error.

Wilyer Abreu’s power adds depth to Boston’s lineup, yet the team’s inability to capitalize late in games has stalled momentum. With their last 10 games producing a 5-5 split and a 6.0 RPG average, the offense is present, but defensive lapses have allowed opponents to keep pace. Against a Marlins team producing at a similar scoring rate, Boston’s recent form leaves them vulnerable to an upset despite their strong season record.

  • Batting Average: 0.254
  • Total Runs Scored: 614
  • Home Runs: 149
  • OBP: 0.325
  • SLG: 0.43

  • WHIP: 1.3

Away Record: 27-34 • Home Record: 39-22
Last 5 Games: 1-4 (5.4 RPG)
