Gallen is listed at 1-2 with a 4.45 ERA, which gives this game a clear scoring route. The 1-0 game yesterday is the scare. The 9-0 result one day earlier shows the ceiling is still live.

ARI -105

Join Discord for earlier access: https://discord.gg/HjKxYKdSUy Pittsburgh has scored 1 run across two listed Chase Field games in this series. Keller owns the cleaner starter card, but the Pirates have been held to 0 or 1 run in 4 of their last 10. Arizona's price is playable because the recent home sample is still 2-1 with an 11-6 run edge.
