Mets vs Nationals Prediction
The Nationals are 8-3 in their last 11 meetings against the Mets and are 4-1 their last 5 meetings in Washington.
In this Mets vs Nationals Prediction, the Mets are coming as -115 road favorites. I don’t trust either pitcher in this matchup as they both have a combined 9.45 ERA and in the previous game this season where they both started, there were 16 total runs scored. All three games in this series have been extremely high-scoring ones, with 23, 15 and 12 total runs and the last five meetings between those two teams this season went over the total. The weather is bad, but I will still go over the low number of 8 in this one.
