🧢 Quinn Priester – Milwaukee Brewers

• Season performance:

  • 8–2 record, 3.33 ERA, 1.20 WHIP across 94.2 innings over 18 games (13 starts)

  • Last 7 starts: 5–0, with a 2.54 ERA, 44 K, and WHIP around 1.05—posting back-to-back strong outings including 10 K over 6 scoreless innings vs. Dodgers on July 18

• Pitching profile:

  • Right‑hander pairing a sinker-slider combo, showing impressive control (WHIP 1.20).

  • Notably high K/9 ~7.6, lower than Castillo but effective when command is sharp

• Trends & outlook:

  • Gaining momentum—seven consecutive wins, most recently shutting down the Dodgers with 10 strikeouts, 0 walks in 6 IP

  • Still young (24), showing signs of breaking through with improved secondary stuff and composure.

✅ Takeaway: When Priester is on, he delivers efficient, swing-miss innings. But he can be vulnerable if Melbourne’s aggressive lineup jumps on mistakes early.

🧢 Luis Castillo – Seattle Mariners

• Season performance:

  • 7–5, 3.21 ERA, 1.21 WHIP, 100 strikeouts over 115 innings from 20 starts

  • Solid recent form: last 7 games — 3–1, 3.02 ERA, 40 K in ~42 IP

• Health & role:

  • Fully recovered from IL stint; regained consistency in rotation

• Stuff & strategy:

  • Mixes four-seamer, sinker, curve, change-up; strikeout rate ~7.8 K/9, walk rate ~2.8 BB/9

  • Park-and-innings-friendly—T-Mobile suits his pitch-to-contact style

• Recent outing:

  • On July 19 vs. Astros: held them to 6 2/3 scoreless innings, 7 K, 3 hits; neighboring win stretched Mariners’ shutout streak to 36 innings

  • That game earned stellar .346 WPA, signaling dominance

✅ Takeaway: Castillo is the steadier veteran—with a solid K/BB ratio, control, and recent strong outings. May not miss bats elite‑ly but limits hard contact effectively.

Milwaukee Brewers vs Seattle Mariners Over/Under Analysis 7

Totals Play: Under 7 — strong pitchers and pitcher-friendly park favor a low-scoring game.

DraftKings

4.5/5

Tip: Bet the Under 7

• Great pitching matchup
• Both teams hitting well
• Bullpen will be key
