PROBABLE PITCHING MATCHUP
Kansas City — RHP Alec Marsh (1–3, 4.66 ERA, 1.33 WHIP)
Marsh has shown flashes of strong strikeout ability, but command issues and home‑run susceptibility remain concerns. His road ERA is slightly higher.
Seattle — RHP Logan Gilbert (3–2, 3.41 ERA, 1.09 WHIP)
Gilbert has been Seattle’s most consistent starter. Elite fastball command, improved splitter, and strong home splits. He matches up well vs. KC’s right‑heavy lineup.
Pitching Edge: Seattle (clear).
