With the win, the Rockies took a one-game lead for the top National League Wild Card spot over the D-backs, who fell to the Astros, 9-5, on Wednesday.
Three runs were all the support Rockies starter Jon Gray needed, as the righty tossed six innings and gave up two runs. Nick Markakis drove in the only Braves runs off Gray -- a two-run single up the middle in the sixth.
