Our Seattle Mariners vs San Francisco Giants Prediction
The Difference Maker: Despite Webb’s current slump (11 earned runs in his last two starts), the Giants are in a strong position to sustain their streak as long as the offense keeps churning out runs. The Giants' batting row averages 5.4 runs in their last five games.
Mariners starter Bryan Woo also isn’t a safe bet to stifle the Giants. Woo surrendered four earned runs over six innings in his last start against the Giants last year.
But the biggest game-changer for this game will be the Giants’ bullpen, which has maintained a 2.70 ERA over the last five games.
What to Expect: Webb earns a win on the mound after benefiting from the Giants’ suddenly prolific offense. San Francisco’s bullpen also gets the job done, denying the Mariners any chance of mounting a comeback.
Our betting prediction for the San Francisco Giants vs. the Seattle Mariners: The Giants will win.
