Team Analysis
Oakland Athletics
The Athletics are 3-2 across their last five games, averaging 5.0 runs per contest, signaling a lineup that has been competitive but inconsistent. Their road record of 33-34 exposes the challenge of translating offense away from home, where run support often dips. Brent Rooker has been a steady contributor, but the team’s pitching staff continues to allow too many scoring opportunities, leaving little margin for error.
Over the last 10 games, Oakland is 6-4 while producing 5.4 runs per game, evidence of offensive balance when Tyler Soderstrom and Shea Langeliers contribute. Still, the Athletics’ 4.82 ERA makes it difficult to sustain winning streaks, particularly against a team like Seattle that can capitalize on power hitting. The lack of road dominance makes them a vulnerable betting side in this spot.
- Batting Average: 0.254
- Total Runs Scored: 584
- Home Runs: 178
- OBP: 0.32
- SLG: 0.434
- OPS: 0.754
- ERA: 4.82
- WHIP: 1.38
Away Record: 33-34 • Home Record: 26-37
Last 5 Games: 3-2 (5.0 RPG)
Last 10 Games: 6-4 (5.4 RPG)
Seattle Mariners
The Mariners have dropped four of their last five, scoring 3.8 runs per game in that span, but their 38-25 home record shows why bettors should still back them at this venue. Cal Raleigh’s power numbers anchor an order that remains dangerous despite recent scoring dips, and the Mariners’ pitching staff has kept their ERA below 4.00, providing stability when the offense lags. Home-field advantage makes a significant difference here, especially against an Athletics team that has struggled to win consistently on the road.
Over the last 10 games, Seattle is 3-7 while still averaging 3.8 runs per game, which reflects inconsistency rather than a collapse. Eugenio Suarez and Julio Rodriguez add depth that forces opposing pitchers into tough spots, and this lineup has repeatedly produced against Oakland in recent meetings. With a superior bullpen and stronger situational splits at home, Seattle holds the betting edge on the moneyline.
- Batting Average: 0.243
- Total Runs Scored: 582
- Home Runs: 180
- OBP: 0.318
- SLG: 0.41

Moneyline Betting Prediction
Seattle Mariners’ superior home record, consistent bullpen, and proven ability to edge Oakland in recent head-to-head contests position them as the clear side. With Cal Raleigh driving runs at a high clip and Eugenio Suarez providing additional power, the Mariners’ offense has the tools to exploit Oakland Athletics’ weaker pitching staff. The Athletics’ road inconsistency reinforces why Seattle is the stronger moneyline play in this matchup.
Confidence sits with the Seattle Mariners based on recent profiles.

In their last five, the Seattle Mariners have produced 3.8 RPG and the Oakland Athletics 5.0. That output frames how this total sets up.
