The Washington Nationals are coming into this contest on the back of six consecutive losses, leaving the field scorless half of the times. A visit to Coors Field could be just what they need to get back on track offensively, and I expect a high-scoring contest in this series-opener against the Colorado Rockies.

Here are my keys to the game:

1. Pitching - The Nats hand the ball to Jordan Zimmermann (8-8, 3.34 ERA) who's overall numbers may look decent enough, but he's way better at home at Nationals Park than on the road where he has a 4.55 ERA in 11 starts on the year. He's a winless 0-3 with a 3.68 ERA overall since the All Star break. The Rockies will counter with David Hale (3-4, 5.69 ERA) who'll make his first start in over a month after spending some time on the disabled list due to a groin injury. He's allowed four runs or more in each of his last five starts, serving up on a homer per game on average in that span and a total of 10 in his last seven starts.

2. Situational - Six of the Rockies last seven and all of Hale's last four home at Coors Field have gone over the total. The over is 8-2 in the Nats last 10 games following an off day.

3. X-Factor - Colorado's relievers rank dead last in the major leagues this season with a 4.83 ERA.
