Anthony Santander was the Rule 5 pick the Orioles kept this season. Here we are in mid-August and they've finally brought him along to the actual big league team, with an injury recovery dragging out Santander being activated from the disabled list until just now.
On Wednesday night, with Santander's 20-day rehab stint maxed out, the Orioles officially put him on the active roster. He had been on the disabled list up until now due to recovering from both offseason shoulder surgery and what was described during spring training as some kind of forearm soreness.
