Mark Zinno thinks the first five innings under is a strong play in the Pirates vs Marlins matchup on Opening Day. He highlighted Miami's starter, Sandy Alcantara, as having a short leash this spring and limited innings heading into the season, suggesting he won't pitch deep into the game. Zinno also noted Miami's bullpen deteriorated significantly following last year's trade deadline, going from surprisingly decent to one of the weakest. Given Marlins' bullpen issues, Zinno strongly implies that if Alcantara exits early, they lose an important pitching edge, creating value on the under through five innings rather than a full game wager where the bullpen becomes a liability. This compounds with Pittsburgh countering with Paul Skenes, a strong pitcher expected to limit Miami's already weak offense.
