The Orioles' Single-A affiliate in Delmarva activated right-hander Miguel Mesa from the 60-day injured list on Monday, Nov. 2.
Mesa, 23, is a native of Pueblo Viejo, DOM. He has not yet made his major league debut.
Coming off the 60-day injured list puts a player back on the 40-man roster, so the move usually comes with a corresponding 40-man transaction.
Also on Nov. 2, High-A Frederick activated right-hander Luis Sánchez from the full-season injured list, High-A Frederick activated right-hander Grabiel Salazar from the full-season injured list and High-A Frederick activated right-hander Hayden Nierman from the full-season injured list.
