Team Analysis

Boston Red Sox

The Red Sox sit at 84-70 overall, carrying a balanced profile but without sustained momentum in recent weeks. Their last 5 games show a 3-2 record with 5.2 RPG, a respectable mark that demonstrates offensive capability but not dominance. Trevor Story has been the steadying presence, yet the team’s 38-38 away record underlines the challenge of translating production into consistent road wins.

Jarren Duran and Wilyer Abreu have offered additional offensive depth, but the Red Sox remain an inconsistent road team that struggles to separate in tight contests. Their 5-5 mark over the last 10 games highlights the lack of rhythm, leaving them vulnerable against a Rays side that matches up well at home. With a neutral trend and no decisive edge away from Fenway, Boston’s outlook in this spot is limited.

  • Batting Average: 0.254
  • Total Runs Scored: 756
  • Home Runs: 182
  • OBP: 0.324
  • SLG: 0.424
  • OPS: 0.748
  • ERA: 3.75
  • WHIP: 1.29

Away Record: 38-38 • Home Record: 46-32
Last 5 Games: 3-2 (5.2 RPG)
Last 10 Games: 5-5 (4.7 RPG)


Tampa Bay Rays

The Rays’ season mark of 75-79 looks underwhelming, but their 40-39 home record provides a foundation for betting value. Their last 5 games stand at 2-3 with 3.8 RPG, a modest number, yet Junior Caminero’s power output ensures they can flip games quickly. Tampa Bay Rays’ ability to produce runs in bursts positions them as a live side against Boston’s neutral form.

Yandy Diaz’s consistency and Brandon Lowe’s balanced production give Tampa Bay a multi-faceted attack that is better supported in their home environment. The Rays’ 3-7 record over the last 10 games reflects inconsistency, but the matchup against a road-split Boston team creates a favorable window. With their lineup depth and situational edge at Tropicana, Tampa Bay projects as the stronger play here.

  • Batting Average: 0.252
  • Total Runs Scored: 686
  • Home Runs: 176
  • OBP: 0.314
  • SLG: 0.404
  • OPS: 0.718
  • ERA: 3.85
  • WHIP: 1.21

Away Record: 35-40 • Home Record: 40-39
Last 5 Games: 2-3 (3.8 RPG)
Last 10 Games: 3-7 (3.7 RPG)

Over/Under Trends

Boston Red Sox’s last 10 games have averaged 8.3 total runs, with 4 games that would have cleared today’s total of 8.

Tampa Bay Rays’ last 10 games have averaged 8.2 combined runs, with 5 games clearing the same number of 8.

Moneyline Betting Prediction

Tampa Bay Rays’ home stability combined with the run-producing ceiling of Junior Caminero, Yandy Diaz, and Brandon Lowe makes them the sharper side despite recent inconsistencies. Boston’s neutral 5-5 stretch and .500 road record fail to project the same upside, giving the Rays the situational edge to secure this matchup.

The Tampa Bay Rays are the sharp side on form and splits.

Over/Under Prediction

Last five form shows the Tampa Bay Rays at 3.8 RPG and the Boston Red Sox at 5.2, giving context for the number.

These teams are combining for 9.0 runs per game recently — above the posted total of 8.0. That points toward the Over 8.0.
