Washington Nationals vs Arizona Diamondbacks Picks

Nationals vs Diamondbacks Spread Pick

  • Take the Diamondbacks (5 units)

Arizona will be starting their ace in Eduardo Rodriguez. The left has been spectacular with a 5-1 record and 2.24 ERA. He also has a 0.84 ERA against the NL East and a 1.34 ERA when pitching at home. The Diamondbacks offense has also supported Rodriguez, as they have won nine of his last 10 starts. The Nationals have been strong this season, but this a tough matchup for them. The pitching efficiency and length of Rodriguez has been tough to overcome even for the league’s best hitters.

Take Arizona to cover.
