STARTING PITCHING MATCHUP

- 2026 ERA: 3.51
- WHIP: 1.12
- K/BB: 4.0
- Last 3 starts: 19.0 IP, 7 ER, 20 K
- Pitch mix: 96 mph 4‑seam, slider, splitter, curve
Gilbert has been excellent, generating weak contact and limiting walks. His fastball/slider combo has been sharp.

- Last 3 starts: 17.2 IP, 6 ER, 19 K
