The visiting Colorado Rockies will vie for their first four-game winning streak of the season on Wednesday night when they play the third contest of their four-game series against the spiraling Washington Nationals. Colorado matched a franchise record with seven home runs in a 10-6 win on Tuesday night. The Rockies are a respectable 7-7 — including an impressive 6-2 on the road — since falling to 9-50 on June 1. “We could have let the start of the season weigh on us and beat us down,” designated hitter Mickey Moniak said.
