Team Analysis

Arizona Diamondbacks

The Diamondbacks hold an 80-79 record and have split their last 10 games at 5-5, showing balanced form despite a 2-3 mark in their last five. This group continues to generate steady offense with 4.4 runs per game in that span, driven by consistent contributions from Geraldo Perdomo and Corbin Carroll. Their road record of 37-42 signals challenges away from home, but the offense has provided enough lift to keep them competitive in high-leverage matchups.

Ketel Marte’s timely production adds another layer of scoring reliability, giving Arizona three dangerous bats capable of carrying momentum. Even with uneven recent results, their ability to average above four runs per outing places them in a strong betting position against a Padres team that thrives at home. With recent totals consistently clearing the posted number, Arizona Diamondbacks’ scoring depth positions them as a live underdog worth backing.

  • Batting Average: 0.251
  • Total Runs Scored: 786
  • Home Runs: 212
  • OBP: 0.325
  • SLG: 0.433
  • OPS: 0.758
  • ERA: 4.44
  • WHIP: 1.32

Away Record: 37-42 • Home Record: 43-38
Last 5 Games: 2-3 (4.4 RPG)
Last 10 Games: 5-5 (4.3 RPG)


San Diego Padres

San Diego enters with an 87-72 record and has surged to a 4-1 mark over its last five games, averaging 4.6 runs per contest. Manny Machado’s run production has been central to that push, while Ramon Laureano has added balance to the lineup. Their 50-29 home record lays bare why they are consistently tough to beat at Petco Park.

Fernando Tatis Jr. has chipped in with power across recent series, keeping the Padres’ offense steady even when opponents apply pressure. However, despite their recent form, San Diego has been vulnerable to teams with multiple power bats, and Arizona fits that profile. With both sides producing around nine combined runs per game, the Padres’ strong home play still faces resistance from a Diamondbacks lineup that matches their scoring pace.

  • Batting Average: 0.252
  • Total Runs Scored: 685
  • Home Runs: 148
  • OBP: 0.321
  • SLG: 0.388
  • OPS: 0.709
  • ERA: 3.64
  • WHIP: 1.21

Away Record: 38-43 • Home Record: 50-29
Last 5 Games: 4-1 (4.6 RPG)
Last 10 Games: 6-4 (4.4 RPG)

The Diamondbacks’ ability to sustain 4.3 runs per game across their last 10 contests, combined with their proven scoring depth from Perdomo, Carroll, and Marte, makes them the sharper side despite San Diego Padres’ home success. Their recent offensive consistency neutralizes the Padres’ edge at Petco Park and sets up Arizona as the more valuable moneyline selection.
