Taking advantage of the edges published on Stats Insider is one of the keys to achieving long-term success as a punter.
Even though the Mets are more likely to cover the line, our best bet of Nationals +1.5 is based on the likelihood of that happening, as suggested by our predictive analytics model, and the best odds available.
