In Friday’s 6-4 home victory over the Giants, Willson Contreras played a key role in the offense, going 1-for-2 at the plate with a home run, one run scored, and three runs driven in.

San Francisco vs. Boston Picks and Prediction

Boston will try to take advantage of a Giants team that has had a difficult season and hasn’t found much consistency. San Francisco will hand the ball to Blade Tidwell, who has posted a 4.33 ERA over 27 innings this year, as he looks to keep a dangerous Red Sox lineup under control. On the other side, Boston will start Patrick Sandoval, who enters the matchup with a 1-2 record and a 4.76 ERA. Sandoval hasn’t been dominant, but the Red Sox will be hoping he can give them a steady outing while their offense puts pressure on the Giants early. Final Score Prediction, Boston Red Sox win 5-4.
