  • Run differential: +22
  • Strength: Speed, athleticism, deep lineup
  • Weakness: Bullpen inconsistency

  • Last 10 games: 3–7
  • Home record: 12–15

STARTING PITCHING MATCHUP

Mike Soroka — RHP, Diamondbacks

  • 2026 ERA: 3.48
  • WHIP: 1.19
  • K/BB: 3.2
  • Last 3 starts: 18.0 IP, 7 ER, 14 K
  • Pitch mix: Sinker, slider, change, curve

Soroka has been excellent at inducing ground balls and limiting hard contact. His sinker/slider combo has been sharp, and he’s been especially effective vs right‑handed hitters.

Concern: Giants’ left‑handed bats (Yastrzemski, Wade Jr., Conforto) match up well vs sinkerballers.

Mason McDonald — RHP, Giants

  • 2026 ERA: 4.71
  • WHIP: 1.38
  • K/BB: 2.7
  • Last 3 starts: 14.1 IP, 11 ER, 12 K
  • Pitch mix: 95 mph 4‑seam, slider, curve, change

McDonald has shown flashes but has been inconsistent. When he commands his fastball, he’s competitive; when he elevates it, he gets hit hard.

Concern: Arizona crushes elevated fastballs and ranks top‑5 in MLB in hard‑hit rate vs RHP.
