Urias was optioned to Triple-A Norfolk on Sunday.
The O's needed some length behind Adam Plutko on Sunday, so they swapped out Urias for lefty Bruce Zimmermann. Urias surprised with his small-sample performance last season, but he has struggled to a .226/.305/.321 line so far in 2021. He will have to spend at least 10 days in the minors unless he's brought back as an injury replacement.
