Nationals vs Mets Prediction 

New York comes into this matchup after winning five of their last six games and they are coming off of a great series win over the Yankees. The Mets are 9-13 on the road this year, while the Nationals are 8-14 at home. Washington has won three of their last five games, but they have allowed at least seven runs in three of those five. The Nationals are starting Irvin, who has allowed nine earned runs over his last 8.0 innings, while Scott has allowed two earned runs or fewer in all four starts, but doesn’t go very deep into games. I don’t like either pitcher, but the Mets finally have some momentum and I like them to win here.
