If you're serious about making a run, then it's all hands on deck. The best hitters and pitchers are called up to the big league club, even if it possibly means starting the clock on them a year "early". Like 2015 with Conforto. That team had terrific pitching, but a terrible offense. Call up Conforto. Get Cespedes. Have Murphy turn into the machine he is now, and suddenly the Mets were on fire. This year, I don't see that they do anything well. The offense is bad. Even if you called up Alonso and hope he is 2015 Conforto, you don't have anything in the minors to bring in the next Cespedes. And the pitching, as we all can see, is nowhere near 2015. In other words, it would take a lot more than Alonso to save this season.
