The Boston Red Sox have a 68-59 record this season and are sitting in 3rd place in the AL East. They have a 31-32 home record and are coming off a 6-7 home loss against the Diamondbacks. They will face the Marlins and the Yankees next.
The Boston Red Sox have a .250 batting average this season, a .323 OBP, and a .405 slugging percentage. The Red Sox’ pitching staff has a 3.52 ERA and a 1.22 WHIP. Willson Contreras leads the Red Sox with a .284 batting average, while leading the team in RBI with 75 and adding a team-high 25 home runs.
Sonny Gray (R) is the projected starting pitcher for the Red Sox, and he has a 15-3 record, a 2.65 ERA, and a 1.15 WHIP.
The San Francisco Giants have a 52-75 record this season and are sitting in 4th place in the NL West. They have a 23-42 road record and are coming off a 2-5 road loss against the Guardians. They will face the Reds and the Diamondbacks next.

Jung Hoo Lee leads the Giants with a .293 batting average. Rafael Devers leads the team in RBI with 69 and adds a team-high 25 home runs.
Logan Webb (R) is the projected starting pitcher for the Giants, and he has an 8-7 record, a 3.50 ERA, and a 1.06 WHIP.
The Giants are 3-1 in their last 4 meetings against the Red Sox but are 1-3 in their last 4 visits in Boston.
In this Giants vs Red Sox Prediction, the Red Sox are coming as -175 home favorites. I like the Red Sox at home in this one with Sonny Gray on the mound, who has been elite at home, with a 6-1 record and 2.45 ERA. Logan Webb has been in excellent form, but the Red Sox have both a superior offense and the best bullpen in baseball, so even if their offense gets contained early, I expect them to build a lead late. Take the Red Sox to win this one.
