The Orioles' Single-A affiliate in Delmarva activated right-hander Denton Biller from the 60-day injured list on Monday, Nov. 2.
Biller, 21, is a native of Kansas City, Missouri. In 2026, Biller posted a 6.43 ERA with 29 strikeouts and 26 walks over 42 innings in 13 Single-A appearances, including 10 starts. He converted one save. 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.
