Team Analysis

San Diego Padres

The Padres’ 3-2 mark in their last five games reflects a team playing steady but not overwhelming baseball, with 4.4 runs per game in that stretch. Their road record sits below .500, indicating a vulnerability when away from home that becomes critical in this matchup. Manny Machado is producing consistently, but the team’s overall rhythm has leaned more toward grinding out wins than dominating opponents.

Over their last 10 games, San Diego has averaged 5.0 runs per contest, showing signs of offensive reliability but not the explosive ceiling that Seattle has displayed. Ramon Laureano has been a steady contributor, while Ryan O’Hearn adds balance to the middle order, but the Padres still lack the sustained firepower that can tilt games on the road. Their pitching metrics remain solid, yet the Mariners’ home advantage and power profile create a sharper betting edge against them.

  • Batting Average: 0.251
  • Total Runs Scored: 554
  • Home Runs: 115
  • OBP: 0.321
  • SLG: 0.385
  • OPS: 0.706
  • ERA: 3.57
  • WHIP: 1.19

Away Record: 32-36 • Home Record: 43-22
Last 5 Games: 3-2 (4.4 RPG)
Last 10 Games: 6-4 (5.0 RPG)


Seattle Mariners

The Mariners have been more volatile in their last 10 with a 3-7 record, yet their offense has surged to 6.0 runs per game across the last five, proving they can overwhelm opponents when the bats connect. At home, their 40-27 mark reinforces their reliability at this venue, where power bats like Cal Raleigh thrive. That combination of recent scoring spike and venue strength makes them the stronger betting side.

Eugenio Suarez has been a steady source of power, while Julio Rodriguez adds dynamic production that stresses opposing pitchers. Despite the recent losing stretch, the Mariners’ ability to generate nearly 11 combined runs per game across their last 10 contests shows they are playing in higher-scoring environments. With their lineup producing at home and the Padres struggling away, Seattle enters with the offensive upside to dictate the pace.

  • Batting Average: 0.242
  • Total Runs Scored: 606
  • Home Runs: 188
  • OBP: 0.318
  • SLG: 0.411
  • OPS: 0.729
  • ERA: 3.96
  • WHIP: 1.26

Away Record: 31-35 • Home Record: 40-27
Last 5 Games: 3-2 (6.0 RPG)
Last 10 Games: 3-7 (4.7 RPG)

Seattle Mariners’ 40-27 home record paired with a consistent scoring lift from Cal Raleigh and Julio Rodriguez creates a decisive edge over a Padres team that has underperformed away from home.

Data supports the Seattle Mariners as the right side.
