The Baltimore Orioles were represented by pitchers Cody Carroll, Dean Kremer, David Lebron and Alex Wells as well as infielders Rylan Bannon and Mason McCoy and outfielder T.J. Nichting in the 2019 Arizona Fall League. The seven played for the Surprise Saguaros, a team comprised of prospects from the Kansas City Royals, the New York Yankees, the Texas Rangers, and the Washington Nationals, in addition to the aforementioned Orioles prospects.
Nichting was a late addition to the team as the original plan was for outfielder Austin Hays to join the Saguaros, but that plan changed based on his performance and number of at-bats with the Orioles in September.
