Join Discord for earlier access: https://discord.gg/HjKxYKdSUy This is a first-five dog, not a full-game Royals statement. Kansas City gets +115 at home against a road favorite. Gilbert has a 4.447 ERA and 11 HR allowed in 56.2 innings, which gives the Royals a direct early-scoring path. Cameron is the risk at 5.40 ERA, but Witt’s .8516028 OPS and 15 SB are enough for one first-five swing at this number.
