Carasiti was optioned
to Triple-A Albuquerque on Tuesday.
Carasiti tossed 2.2 scoreless innings of relief during his three-day stay in the Rockies' bullpen, but the 32-year-old right-hander holds a 6.29 ERA in 16 total major-league appearances this year. Ryan Feltner
(head) has been activated from the injured list in a corresponding move and will start Tuesday's game at San Diego.
