First pitch 6:45 p.m. ET
Venue: Fenway Park, Boston, Massachusetts
TV: CLEG / NESN / MLB.TV
The Guardians hold a slim one-game lead over the White Sox in the AL Central and are fighting for a division title (and potential No. 2 seed/bye) with six games left. The Red Sox sit third in the AL East and are in the wild-card mix or fighting for seeding. This opens a three-game series at Fenway.
Starting Pitchers
Cleveland LHP Parker Messick (12-9, 2.57 ERA, 1.03-1.04 WHIP, 178.1 IP, 186 K, 47 BB, 17 HR)
One of the AL’s top young arms with elite control and strikeout ability (high K/9, low WHIP). Strong recent form, including quality starts against division foes. Road numbers solid. Faces a Red Sox lineup that has been inconsistent.
Boston LHP Payton Tolle (9-6, 3.02 ERA, 1.06-1.07 WHIP, 143.0 IP, 166 K, 38 BB, 15 HR)
Impressive rookie/sophomore campaign with strong strikeout rates and command. Effective overall; lefty-on-lefty dynamics could play a role against Cleveland’s mix of hitters. Solid home numbers expected at Fenway.
Venue & Weather Forecast
Fenway Park is a historic, hitter-friendly venue with the Green Monster in left field favoring pull hitters and unique dimensions.
Forecast for first pitch: Mostly cloudy to partly sunny, high near 63°F, dropping to the low-to-mid 50s overnight. Northeast winds 10-13 mph. Low precipitation chance (near 0- few percent). Cool, dry conditions favor pitchers and could keep scoring down.

Key Player vs. Player Matchups & Roster Notes
Messick’s elite command vs. Boston’s mix of contact and power (potential absences in the middle of the order).
Tolle’s high-K lefty stuff vs. Cleveland’s lefty-heavy or balanced lineup (Kwan, Ramírez as anchors).
DeLauter and Ramírez provide Cleveland power/speed; Boston relies on available bats for production at the Monster.
Both clubs feature strong pitching staffs overall (Guardians top-10 ERA; Red Sox similar). Late-season lineups will emphasize playoff evaluation and health management.
Recent Team Forms
Guardians: Hot – five-game winning streak (swept Athletics, took series from White Sox), 7-3 in last 10. Strong at the right time for the division race. Away record 40-35.
Red Sox: Cooler – dropped two of three at Tampa Bay, 4-6 in last 10. Home record 38-37. Inconsistent but capable of strong stretches.
Season Series History
Red Sox lead the 2026 season series 2-1 from a May set in Cleveland (Boston took the final two games by wide margins after a Guardians win). Competitive earlier meetings; this is the first 2026 series at Fenway.
Betting Trends
Guardians strong recently and as road underdogs in spots; Red Sox solid at home but recent form mixed. Both starters post low ERAs/WHIPs, supporting a low-scoring game. Cool weather further favors Unders.
