San Francisco’s strongest area is its hitting production relative to Seattle. The Giants lead the Mariners by 28 points in batting average, 114 hits, 10 runs, one point in on-base percentage, and 43 points in slugging percentage. Their recent run prevention has also been impressive, with only nine runs allowed across the last five games. The primary weakness is a pitching staff that trails Seattle in every provided season pitching category.

San Francisco Giants vs Seattle Mariners Picks and Prediction
San Francisco Giants vs Seattle Mariners Pick
- Pick: Seattle Mariners Moneyline
I am taking Seattle on the moneyline because the Mariners hold the better overall and home records while owning substantial advantages in the season pitching statistics. Seattle’s scheduled starter has a 3.32 ERA, a 0.99 WHIP, and 119 strikeouts against only 24 walks. San Francisco is in much better recent form and won the latest matchup 7-0, but Seattle’s starting-pitcher advantage, 27-21 home record, and stronger team pitching numbers make the Mariners my selection to respond.
San Francisco Giants vs Seattle Mariners Total Pick
- Pick: Under 7.5
Take the under if the total is set at 7.5. I am backing the under because both probable starters have ERAs below 3.40, and Seattle’s starter owns a 0.99 WHIP. San Francisco has held four of its last five opponents to two runs or fewer, including a shutout in the recent meeting. Seattle has also scored two runs or fewer in three of its last four games. With strong starter numbers and Seattle’s recent offensive struggles, I expect the scoring to remain limited.
Final Score Prediction: Seattle Mariners 4 – San Francisco Giants 2
