D-backs @ Rockies discussion

The Arizona Diamondbacks take on the Colorado Rockies at Coors Field with Merrill Kelly starting against Mason Adams. Arizona sits four games back of a three-way tie for the National League wild-card spots with reported playoff odds of 7.4 percent. The team aims to make up ground on the San Diego Padres to keep their postseason chances alive.

Kelly carries an earned run average of 5.00 into the start, having previously thrown a complete game against Colorado in Denver earlier this season. Reliever Kevin Ginkel recently logged his 71st bullpen appearance of the campaign, becoming one of few Arizona pitchers to reach seventy games in recent seasons.
