The Rockies recalled Smith from Triple-A Albuquerque on Wednesday.
Since he's being designated as the Rockies' 27th man for Wednesday's doubleheader with the Marlins, Smith is eligible to rejoin the big club one day after being optioned to Triple-A. The 26-year-old right-hander made his MLB debut over the weekend in Washington, striking out one in a scoreless inning of relief. He'll likely be returned to Albuquerque following the twin bill.
