When the Baltimore Orioles finalized their opening day roster, there were some surprises on it, notably the omission of Grayson Rodriguez. He isn't the only one, although he is the most notable one. In the spirit of the inevitable roster turnover, here are three current players on the roster who won't be in Baltimore when the calendar turns to May.
Three members of the Baltimore Orioles won't be on the roster in May
Anthony Bemboom
Currently serving as the backup to Adley Rutschman, Bemboom is a certainty to be off the roster by May 1. He was DFA'd last year when Rutschman was called up, and he'll be DFA'd once again when James McCann gets activated from the IL. While Bemboom is a fine option as a backup catcher, McCann is a better one, so Bemboom will not be on the roster by the start of May.

Mike Baumann
Recently converted to a short reliever, Mike Baumann was able to crack the opening day roster over Joey Krehbiel. Before play on Wednesday, he's appeared in two games and allowed one run in 2 2/3 innings. Baumann to me seems like a placeholder until one of Mychal Givens or Dillon Tate return from the 15 Day IL, so it's reasonable to assume he'll be gone when they're both healthy.

Logan Gillaspie
Logan Gillaspie is another member of the Orioles bullpen who I feel like made the roster because of the injuries to Tate and Givens. While Gillaspie was solid last year and has 1 2/3 scoreless innings under his belt this season, he also figures to be an odd man out when Tate and Givens are healthy.
Now, this isn't a knock on Gillaspie, as he's a fine option out of the bullpen, but he just doesn't have the reliability and track record of Tate and Givens. Therefore, I suspect he'll be down in Norfolk in due time.
