Pitching Matchup Breakdown
San Francisco — Robbie Ray (LHP)

Last 5 Starts: 1–3, 4.60 ERA
Splits:
Road ERA: 4.55

Profile: Ray relies on a high‑velocity fastball and sweeping slider. When his command is sharp, he’s dominant; when not, he’s vulnerable to walks and HRs. T-Mobile Park’s pitcher‑friendly conditions help him, but Seattle’s right‑handed bats match up well.
