The Rockies designated Martini for assignment Friday. Martini was a lineup regular against right-handed pitching through the first two months of the season, but he failed to take advantage of the playing time with a .225/.288/.294 slash line in 111 plate appearances. Sam Hilliard was selected to the major-league roster in a corresponding move.

Second baseman Thairo Estrada has been reinstated from the 60-day injured list and immediately inserted into the cleanup spot for his Colorado Rockies debut against the New York Mets
