Nationals vs Mets Prediction 

New York won game one in this series in blowout fashion on Tuesday night and they are hoping this is the beginning of a streak, as they are still 5.5 back in the East. The Mets are 26-34 on the road this year, while the Nats are 24-39 at home. Washington has allowed 19 runs in their last two games and they are starting Lord, who has allowed two earned runs or fewer in four of his last five starts. New York is going with Senga, who has had some struggles over the last few weeks. I don’t love how Senga is pitching right now, but this Washington bullpen is horrible. Take the Mets -1.5 here.
