The Orioles optioned Wells to Triple-A Norfolk on Wednesday.
Wells' stint with the big club lasted just three days before he was cast off the active roster to make room for Tanner Scott (knee), who was reinstated from the 10-day injured list. The 24-year-old rookie made an appearance out of the bullpen in Tuesday's 9-4 loss to the Tigers, giving up a run on three hits while striking out a batter.
