Padres vs Marlins Prediction
Alcantara and plus money is always worth a look, as he’s one of the best arms in the sport when at his best. The problem is the Marlins have run out of gas over the last month and just don’t pack the betting value they once did. The Padres can’t lose these days, and they’re cruising toward a playoff berth. I’m just not excited to step in front of these Padres in their current form. Give me the Padres and he cheap price as they gear up for the postseason.
