Team Analysis

Cleveland Guardians

Cleveland Guardians’ overall record of 68-68 reflects a team unable to sustain momentum, and their 2-3 mark over the last five highlights inconsistency. Averaging 4.4 runs per game in that span shows some scoring ability, but the dip to 2.9 across the last ten highlights a lack of rhythm. Jose Ramirez continues to be the most reliable offensive piece, yet his production has not been enough to mask the team’s broader scoring volatility.

The Guardians’ 33-36 road record further weakens their outlook, especially against a Boston team that thrives at Fenway. Kyle Manzardo has added some power depth, but the lineup’s inability to string together consistent run support remains a concern. With Steven Kwan’s contact skills not translating into sustained rallies, Cleveland enters this series at a clear disadvantage.

  • Batting Average: 0.223
  • Total Runs Scored: 523

  • OBP: 0.294
  • SLG: 0.366
  • OPS: 0.66
  • ERA: 3.94
  • WHIP: 1.32

Away Record: 33-36 • Home Record: 35-33
Last 5 Games: 2-3 (4.4 RPG)

Boston Red Sox

Boston’s 77-62 record and 44-27 dominance at home speak to a team that capitalizes on venue advantage. Their 3-2 mark over the last five games with 5.4 runs per outing shows steady offensive execution. Trevor Story has been a central force in run production, giving the lineup a reliable anchor in key situations.

The Red Sox’s 7-3 run across their last ten games, averaging 4.4 runs, confirms their consistency against both strong and middling opponents. Wilyer Abreu’s balanced power and Jarren Duran’s ability to extend innings with timely hits keep pressure on opposing pitchers. This combination of depth and home-field confidence makes Boston the superior side entering this matchup.

  • Batting Average: 0.253
  • Total Runs Scored: 684
  • Home Runs: 167
  • OBP: 0.325
  • SLG: 0.425
  • OPS: 0.75
  • ERA: 3.69
  • WHIP: 1.29

Moneyline Betting Prediction

Boston’s superior 44-27 home record, combined with their 7-3 surge in the last ten games, highlights their reliability at Fenway against a Cleveland team struggling on the road. With consistent production from Trevor Story and support from Wilyer Abreu and Jarren Duran, the Red Sox are positioned to control the matchup and extend their head-to-head dominance.

Data supports the Boston Red Sox as the right side.

Over/Under Prediction

Last five form shows the Boston Red Sox at 5.4 RPG and the Cleveland Guardians at 4.4, giving context for the number.

These teams are combining for 9.8 runs per game recently — above the posted total of 9.0. That points toward the Over 9.0.
