[D’backs.com] Ahmed slugs grand slam for focused D-backs - The win lifted the D-backs to 53-52, and they remain within shouting distance at 2 1/2 games behind the Nationals for the National League’s second Wild Card spot. But they have to pass four teams and would need to get on an extended winning streak, which is something that has proven elusive for them this year. One thing that has been in plenty of supply is effort and resilience, something they displayed again Saturday. After falling behind 1-0 when Miguel Rojas led off the bottom of the first with a homer, the D-backs rallied for six runs against Marlins starter Jordan Yamamoto in the fourth inning.
