Veen is not in the lineup for Wednesday's game against the Nationals.
The left-handed-hitting Veen will hit the bench against a right-handed starter (Matt Waldron) for the first time since being called up from Triple-A Albuquerque on Aug. 11. Veen homered in his first two games this season, but over his last eight contests, he's gone 3-for-18 with a 0:10 BB:K. Jake McCarthy, Cole Carrigg and Mickey Moniak will play the outfield, and Troy Johnston will serve as the designated hitter for the Rockies on Wednesday.
