The NL West-leading Colorado Rockies locked up a playoff berth for the second straight season, beating the Washington Nationals 5-2 on Friday night for their eighth win in a row behind a resilient start from Kyle Freeland. David Dahl homered for the fifth consecutive game and Ian Desmond hit a two-run homer against his former team to help Colorado clinch at least a wild card with two games remaining. The Rockies entered the night with a one-game lead over the Los Angeles Dodgers as they try to wrap up the franchise's first division crown.
