Team Analysis

Seattle Mariners

Seattle Mariners’ 73-68 record reflects a team that has maintained a winning edge across the season, but their recent 1-4 skid over the last five games highlights a slump that needs correcting. Despite the downturn, the Mariners still average over four runs per game during this stretch, showing that their offense is generating chances even in losses. Cal Raleigh’s power numbers keep opponents wary, and his ability to drive the ball deep offers a stabilizing factor for a lineup that otherwise needs steadier production on the road.

Julio Rodriguez’s balanced hitting gives Seattle another critical dimension, especially when paired with Eugenio Suarez’s run-driving capability. While the Mariners have struggled away from home with a 33-41 road record, their overall offensive ceiling remains higher than Atlanta Braves’, and their superior home run production indicates they can flip tight games quickly. This profile, even amid recent inconsistency, positions them as the more reliable moneyline side in this matchup.

  • Batting Average: 0.241
  • Total Runs Scored: 649
  • Home Runs: 205
  • OBP: 0.318
  • SLG: 0.412
  • OPS: 0.73
  • ERA: 4.03
  • WHIP: 1.26

Away Record: 33-41 • Home Record: 41-27
Last 5 Games: 1-4 (4.4 RPG)
Last 10 Games: 3-7 (4.3 RPG)


Atlanta Braves

Atlanta Braves’ 64-77 record and a 2-3 mark over the last five games illustrate a team lacking rhythm. Their offense has been capped at just 4.0 runs per game during this stretch, which prevents them from building momentum even when pitching holds up. Matt Olson has delivered power but not consistently enough to tilt outcomes, leaving the Braves vulnerable against higher-ceiling lineups.

Michael Harris II and Austin Riley offer secondary production, yet the Braves’ home record of 34-34 shows mediocrity rather than dominance on their own field. With just 159 home runs across the season, Atlanta lacks the explosive scoring punch to cover for their bullpen’s 4.37 ERA. That imbalance makes them the less trustworthy side, particularly against a Seattle team that has shown superior season-long efficiency at the plate.

  • Batting Average: 0.244
  • Total Runs Scored: 624
  • Home Runs: 159
  • OBP: 0.319
  • SLG: 0.394
  • OPS: 0.713
  • ERA: 4.37
  • WHIP: 1.31

Away Record: 30-44 • Home Record: 34-34
Last 5 Games: 2-3 (4.0 RPG)
Last 10 Games: 4-6 (4.2 RPG)

Over/Under Trends

Seattle Mariners’ last 10 games have averaged 9.5 total runs, with 5 games that would have cleared today’s total of 9.5.

Atlanta Braves’ last 10 games have averaged 9.1 combined runs, with 4 games clearing the same number of 9.5.

Moneyline Betting Prediction

Seattle Mariners’ superior power metrics and season-long win rate make them the sharper side, especially after proving their ability to break games open as seen in their recent double-digit scoring win in Atlanta. With Rodriguez and Suarez driving consistent run support, Seattle Mariners’ profile outweighs Atlanta Braves’ stagnant home form and positions them as the clear moneyline play.

Confidence sits with the Seattle Mariners based on recent profiles.

Over/Under Prediction

In their last five, the Atlanta Braves have produced 4.0 RPG and the Seattle Mariners 4.4. That output frames how this total sets up.

These teams are combining for 8.4 runs per game recently — below the posted total of 9.5. That points toward the Under 9.5.
