Fenway Park, Boston, Massachusetts
First pitch: 7:10 p.m. ET
TV: NESN / NBCS Bay Area
This interleague series opener features two contrasting clubs. The Red Sox sit third in the AL East and remain in the wild-card mix, while the Giants own one of the worst records in baseball and have struggled mightily on the road (23-42). It marks the first meeting between the teams in 2026 and includes Rafael Devers’ return to Fenway Park after his trade from Boston to San Francisco.
Starting Pitchers
San Francisco: RHP Logan Webb (8-7, 3.50 ERA, 1.06 WHIP, 110 K in 139.0 IP). The Giants’ ace has been sharp recently, allowing just two runs over 20 innings in August. He induces a high ground-ball rate and limits hard contact. Career notes vs. Boston are limited/mixed (0-1, 5.63 ERA in three prior starts against them in available data).
Boston: RHP Sonny Gray (15-3, 2.65 ERA, 1.15 WHIP, 117 K in 132.2 IP). One of the AL’s most consistent starters this year with excellent command and a strong win-loss record. He has a solid career mark against the Giants (4-1, 3.16 ERA in nine starts). Gray has been particularly effective at home and has not allowed a run in two of his last three outings.
Gray holds the edge in form and overall season performance.
Current Rosters (Key Active Contributors)
Giants core: Rafael Devers (1B, 25 HR / 69 RBI – returning to Fenway), Jung Hoo Lee (OF, .293 AVG), Willy Adames (SS), Bryce Eldridge (DH/power), Luis Arraez (when available), Drew Gilbert, and supporting pieces. Rotation/bullpen features Webb, Landen Roupp, and others.
Red Sox core: Willson Contreras (1B, .284 AVG, 25 HR / 75 RBI), Ceddanne Rafaela (CF), Wilyer Abreu (RF), Jarren Duran (LF), Adley Rutschman (C), Caleb Durbin (3B), and others. Rotation/bullpen includes Gray, with Aroldis Chapman handling late innings.
Injury Reports
Giants: Matt Chapman (60-day IL, abdomen/leg – season-ending surgery), Harrison Bader (60-day IL, plantar fasciitis), Marcelo Mayer (10-day IL, forearm – rehabbing, possible late-August return), Jesus Rodriguez (10-day IL, elbow), Casey Schmitt (10-day IL, knee), Keaton Winn (15-day IL, elbow), plus longer-term absences including Trevor McDonald, Matt Gage, Joel Peguero, and others (mostly elbows). Logan Webb was listed day-to-day with a shoulder note earlier but is expected to start.
Red Sox: Trevor Story (60-day IL, abdomen/sports hernia – progressing in rehab, possible near-term return), Roman Anthony (60-day IL, wrist/finger), Isiah Kiner-Falefa (60-day IL, forearm), Masataka Yoshida (10-day IL, hamstring), Garrett Whitlock (15-day IL, elbow), Johan Oviedo (60-day IL, elbow), plus additional pitching injuries (Garrett Crochet, Zack Kelly, etc.).
Both teams are dealing with significant absences, particularly in the infield and bullpen depth.
Weather Forecast (Boston)
Mostly cloudy with a chance of showers (around 40-50% at times). Highs in the low-to-mid 70s °F (around 70–73°F). Northeast winds 8–15 mph. Conditions should be playable but cooler and potentially damp; monitor for any light rain impact.
Recent Team Forms
Giants (last 10: 3-7): .219 team BA and 3.80 ERA in that span; outscored by 15 runs. They have dropped eight straight road series and continue to struggle away from Oracle Park. Recent results include a 1-0 win at Cleveland mixed with losses.
Red Sox (last 10: 4-6): .271 BA and 3.77 ERA; outscored opponents by 11. Offense has shown life at times (strong series vs. Arizona earlier), but consistency has been an issue. They had a much-needed day off Thursday after a heavy stretch.
Boston holds clear advantages in record, home play, and overall roster quality.
Season Series History
First meeting of 2026. Historically competitive in limited recent interleague play (split results in prior years’ series). Devers’ presence adds a narrative layer for Boston fans.
Key Player Matchups / Notes
Gray’s track record vs. Giants hitters (including Devers 6-for-21 historically in available data) favors the veteran.
Webb’s sinker/changeup mix will test Boston’s contact-oriented bats (Contreras, Rafaela, Abreu have mixed prior results).
Power potential: Devers and Contreras (both with 25 HR) vs. opposing staffs.
Fenway’s dimensions can reward opposite-field contact and extra-base hits.
Bullpens will matter late—Chapman remains a high-leverage weapon for Boston.
Betting Trends
Boston has been a solid home favorite in many spots; totals have trended under in Gray’s recent outings and in some H2H history. Giants struggle as road underdogs.

San Francisco Giants 7.5
