Injury Report
Seattle Mariners
- J.P. Crawford — Probable (ankle soreness)
- Ty France — OUT (wrist fracture)
- Matt Brash — OUT (elbow)

Pitching Matchup Breakdown
SEA — Emerson Hancock (RHP)
Record: 4–3 ERA: 3.76 WHIP: 1.24 K/BB: 52/17 Last 3 Starts: 3.60 ERA, 1.18 WHIP
Profile: Hancock has taken a step forward in 2026, showing improved command of his sinker/slider combo. He induces ground balls and avoids big innings when he keeps the ball down.
Keys to Success:
- Keep sinker low vs. Abrams and Meneses
- Avoid middle‑middle fastballs — Nats hit velocity well
- Get ahead early to use slider as a put‑away pitch
WSH — Miles Mikolas (RHP)
Record: 5–4 ERA: 4.22 WHIP: 1.31 K/BB: 48/12 Last 3 Starts: 4.50 ERA, 1.35 WHIP
Profile: Mikolas is a veteran command‑first pitcher who relies on soft contact and early‑count strikes. When his cutter and sinker are sharp, he can neutralize RH hitters. When they drift, he becomes hittable.
Keys to Success:
- Keep cutter inside vs. Julio Rodríguez
- Avoid falling behind — Seattle punishes fastball counts
- Induce ground balls to escape traffic
Key Player Matchups
1. Julio Rodríguez (SEA) vs. Miles Mikolas
- J‑Rod has been heating up
- Mikolas must avoid giving him elevated cutters or sinkers
2. CJ Abrams (WSH) vs. Emerson Hancock
