Coby Mayo, third base
Mayo will likely start the season in Triple-A Norfolk, but he was also invited to big league camp as a non-roster invitee. Mayo, the game's 30th best prospect according to MLB Pipeline, was ranked by Baseball America as the third best prospect in the Orioles system, behind only Holliday and Basallo.
A graduate of Marjory Stoneman Douglas High School in Parkland, Florida, Mayo was originally signed to go play college ball at the University of Florida. He was a fourth-round draft choice by the Birds in the 2020 MLB Draft and still earned a signing-bonus in excess of $1.75 million. It was an easy decision not to become a Gator.
Projected as one of the best pure power hitters in the draft, Mayo has lived up to his reputation, as he slugged 29 home runs last season between Double-A Bowie and Triple-A Norfolk. He was the Eastern League Player of the Year despite only playing a half season with the Baysox.
