The 27-year-old Ravelo, hitting .333 with nine homers and 42 runs batted in at Memphis this season, will take the palce of righthanded reliever Mike Mayers on the 40-man roster. Mayers, who won’t be able to pitch for the Cardinals for probably another month after suffering a strained lat, was moved from the 10-day injured list to the 60-day IL. He had been hurt in mid-April.
Ravelo has played 838 career minor-league games, including stints with the Chicago White Sox and Oakland organizations. The 6-foot-2, 225-pound Havana, Cuba native was signed by the Cardinals as a minor league free-agent in April of 2017.
