The Boston Red Sox return to Fenway Park on Tuesday, September 8, 2026, for a 6:45 PM ET showdown against the Los Angeles Angels. Patrick Sandoval takes the mound for Boston against Angels left-hander Reid Detmers in what shapes up as an intriguing pitching duel. With September in full swing and every game carrying real regular-season weight, this is exactly the kind of mid-week home date the Sox need to capitalize on. First pitch is on NESN, with radio coverage on WEEI 93.7.
Probable Pitchers: Patrick Sandoval vs. Reid Detmers
Patrick Sandoval gets the nod for Boston. A left-handed starter with a fluid, deceptive delivery, Sandoval has the kind of arsenal — heavy on movement, light on ego — that can keep opposing lineups off-balance. The Red Sox will need him to command the strike zone early and work deep into the game if the bullpen is going to stay fresh this late in the season.
Opposing him is Reid Detmers, the Angels' young left-hander who has shown flashes of front-of-rotation potential during his career. Detmers relies on a sharp breaking ball and solid command to navigate lineups, and he is capable of keeping runs off the board against even the most dangerous offenses. Boston's right-handed bats will have a particular assignment when they dig in against him.
Keys to Watch in Tuesday's Game
- Work the count early: Detmers is most dangerous when he is ahead in counts. The Red Sox lineup needs to grind at-bats, force him into deep counts, and make him throw his secondary stuff in hitter-friendly situations.
- Sandoval's first-inning command: Left-on-left matchups will be plentiful with Detmers on the other side. Sandoval's ability to establish himself quickly and avoid the big inning will set the tone for the entire night at Fenway.
- Late-inning bullpen management: September rosters are expanded, but smart usage still matters. How Boston's manager deploys the relief corps — especially in close, late situations — could easily decide this one.
- Fenway's short porch in right: The Green Monster looms large for right-handed Angels hitters. Sandoval will need to pitch to contact carefully and trust his defense on balls hit to the outfield gaps.
Prediction
This one has the feel of a tight, low-scoring game. Both starters are capable of pitching into the seventh, and neither bullpen is going to give runs away easily. The edge goes to Boston at home, where Fenway's atmosphere and a familiar mound give Sandoval a genuine advantage. Expect the Sox to scratch out enough offense to win a 3-2 type ballgame — the kind of September Tuesday night win that feels small in the moment and enormous in the standings later.
Prediction: Red Sox 3, Angels 2.
