SERIES HISTORY

At Fenway Park: Red Sox lead 13–4

Last meeting (2025): Red Sox 9, Athletics 2

Key trend: Boston’s left‑field dimensions consistently punish Oakland’s fly‑ball‑heavy pitching staff.

KEY PLAYER MATCHUPS

1. Rafael Devers (BOS) vs Joe Perkins (OAK)

Perkins’ fastball/slider combo vs Devers’ elite bat speed. Devers crushes right‑handed pitching (.310 AVG, .580 SLG in 2026). Perkins must avoid middle‑in fastballs.

2. Brent Rooker (OAK) vs Grant Tolle (BOS)

Rooker’s right‑handed power vs Tolle’s sweeping slider. Rooker has a .920 OPS vs left‑handed pitching this season, making him Oakland’s best chance for run production.

3. Jarren Duran (BOS) vs Shea Langeliers (OAK)

Duran’s speed vs Langeliers’ arm. If Duran reaches base, Boston’s small‑ball pressure increases dramatically.

4. Triston Casas (BOS) vs Mason Miller (OAK)

If Casas plays, his patience vs Miller’s elite velocity is a key late‑inning duel. Casas rarely chases, making him a difficult matchup for Miller’s high‑octane fastball.
