The Cubs have the slight edge in the binding model and bring the hotter overall offense, while Petco Park and the marine layer should keep the scoring in a modest range. San Diego’s bullpen has been taxed recently, and both starters profile as playable but not dominant, which gives Chicago a path to enough late offense to edge it. What could go wrong is a strong Michael King outing at home, but the Cubs’ better run production and recent form make them the safer side.
