Bats waking up in the desert – D-backs averaging 10 hits & .278 BA last 10 games. Pirates rank 28th in BA (.224), score just 3 runs/game. At home, AZ thrives – 73 HR (5th in MLB), 5.0 runs/game. Pirates can't win on the road – 6-19 away, just 19-35 overall. Offense anemic outside PNC Park. Diamondbacks returning home from road trip, energy boost + manager calling this a “gut-check” game. Clubhouse urgency at all-time high – big response expected. Heaney struggles vs AZ – 7.71 ERA in 2 career starts. Ryne Nelson just held LAD to 1 run over 5 IP – confidence builder. Pitching edge goes to AZ despite ERAs. Motivation, matchup history, and momentum all favor Snakes to bounce back hard.
