Join Discord for earlier access: https://discord.gg/HjKxYKdSUy Arizona is 8-2 over its last 10 and has allowed only 2.5 runs per game in that stretch. Seattle is 29-29, missing Cal Raleigh, and still being priced like the cleaner side at home. Ryne Nelson's 1.18 WHIP gives the dog enough of an attached-game path against Bryan Woo.
