The Oakland A’s called up catcher prospect Sean Murphy on Sunday, the team announced. To make room on the 40-man roster for Murphy and the return of pitcher Sean Manaea from the injured list, pitcher Tanner Anderson and infielder Corban Joseph were designated for assignment. The 25-man roster is no longer a consideration because Sunday is Sept. 1, so active rosters have expanded for the rest of the season.
Entering the year, Murphy was considered one of the A’s three blue-chip prospects. He was ranked in the team’s top three by every relevant source, including our own Community Prospect List, and he was on every major Top 100 national list, often in the Top 50.
