Alomar, who works as a special assistant for the organization, will take his place at the club's table for the second consecutive year, and he will be joined by Jay Stenhouse, vice president of communications.
Commissioner Bud Selig will announce the first-round picks, but it will be up to Alomar and Stenhouse to phone in each selection and also announce the sandwich picks between the first and second rounds.
It's yet another event in what will be a busy summer for Alomar, who is set to become the first player to be inducted into the Hall of Fame wearing a Blue Jays cap.
Alomar spent five years in Toronto and was an integral component of the club's back-to-back World Series championships in 1992 and 1993. He won 10 Gold Gloves and four Silver Sluggers for his work at second base during his 17-year career.
Toronto has seven selections in the first 78 picks, with the top pick at No. 21 of the first round.
