San Diego activated Morejon (elbow) from the 60-day injured list Tuesday and optioned him to Triple-A El Paso.
Morejon is recovered from the elbow sprain he suffered back in mid-March, but the Padres will keep him on the farm for now. He allowed four earned runs over 4.2 innings (four appearances) during a recent rehab stint at Low-A Lake Elsinore.
