The Colorado Rockies turned a tight game into a runaway with a 13-1 victory over the Washington Nationals at Nationals Park. Colorado scored four times in the fifth inning, four more in the seventh and five in the eighth, overwhelming a Washington club that managed only one run after the second. Tanner Gordon controlled the middle innings with seven strikeouts-free? 5 strikeouts over 7.0 innings, giving the Rockies both the decisive performance and a rested bullpen.

Gordon's seven innings were the game's central pitching edge. He allowed Washington no scoring after the second inning, kept hitters off balance with a five-strikeout performance and carried the game deep enough to eliminate pressure on Colorado's relievers. Washington's Andres Chaparro was the lone consistent offensive answer, going 3-for-4 with a home run and the Nationals' only RBI, but the rest of the lineup could not sustain traffic against Gordon. Will Dion worked 2.2 innings with three strikeouts for Washington, while Luis Perales added two innings and three strikeouts, yet neither outing could contain Colorado's late surge.

The win moved Colorado to 52-81 and gave the Rockies a clean blueprint for finishing games: Gordon set the tempo, the lineup converted opportunities and the bullpen stayed out of extended duty. Washington fell to 62-73 after allowing 13 runs and will need sharper run prevention in the middle and late innings, because Chaparro's three-hit showing could not offset a lineup that produced almost nothing beyond the second. Colorado leaves Nationals Park with momentum built on execution, not a single fortunate break.
