Castro scratched from Rockies lineup due to back stiffness

1:56 AM UTC

PHOENIX -- A Rockies lineup that has struggled to score runs recently went into Saturday night without a player who has been productive of late -- , who was scratched because of low back tightness.

Castro, 8-for-24 (.333) in his last eight games entering Saturday, took grounders at Chase Field before the Rockies announced that he was out of the lineup. His removal came a day after the Rockies placed one of their better hitters this season, outfielder Mickey Moniak, on the 10-day injured list with right ankle tendinitis.

Against Diamondbacks righty Zac Gallen, the Rockies planned to use Castro in the cleanup spot in the lineup.

The offense has scuffled in May as the team has gone 6-14, with four losses by two runs and two others by one. The Rockies also entered Saturday without a home run in a franchise-record-tying seven straight games.
