Final Mariners-Nationals Prediction & Pick

The Nationals are sitting in third place in their division, well behind the Braves and Phillies, and ahead of the Mets and Marlins. This should be where the Nationals end up too. They are a middle-of-the-road team with the ability to go on runs and win large chunks of games. They are in a valley right now though, struggling to get wins. The Mariners are not a good offense, but the pitching has made up for that. They have pitched very well, and the Nationals do not have the offense to overcome that.
