Arizona has the edge tonight with Tanner Bibee’s biggest weakness exposed. He’s giving up 1.45 HR/9, and Chase Field doesn’t forgive mistakes. One swing from the D-backs middle order can flip this game fast. That’s the cleanest path to a home win. Eduardo Rodríguez isn’t perfect with a 5.40 ERA, but his strikeout punch at 9.08 K/9 gives him the tools to strand runners when needed. If he limits traffic early, he can hand this game to Arizona’s bullpen with a lead, which is all the D-backs need. Series urgency also matters. Arizona already dropped Game 1 and can’t afford to fall behind at home. With the roof closed, no weather randomness plays in. Execution wins, and the D-backs have the power bats and strikeout arm to even this series.
