Did Cespedes Win the NL East?

What I’ve found is most of the people that support the Yoenis Cespedes trade is he transformed the offense, and he was the reason the Mets won the NL East. Other people say while Cespedes was great with the Mets, there were other more important factors helping the Mets win the NL East. These arguments rest upon the Mets getting healthy and a weak August schedule. 

I think the best way to look at this is just to present the facts. I’m presenting them unadulterated and without comment. Before presenting them, remember that Cespedes’ first game with the Mets was 8/1. 

Pre-Cespedes Record: 53 – 51

Post-Cespedes Record: 37 – 21 

In the same time frame, here is the Nationals record:
