The San Francisco Giants are expected to promote Zack Minasian, the team's VP of professional scouting, to general manager, reports USA Today's Bob Nightengale.

The news was initially revealed by former major-league manager Bobby Valentine in a post on X that has since been deleted. Nightengale confirmed the news soon thereafter.

Minasian will work under new president of baseball operations Buster Posey, the former National League MVP and three-time World Series champion who was part of the Giants' ownership group and on the team's board of directors. In that capacity, Posey was already familiar with Minasian.

If that last name looks familiar, that's because Zack Minasian is the brother of current Los Angeles Angels GM Perry Minasian, who recently signed a contract extension to stay in that role through the 2026 season. Two brothers working as MLB general managers at the same time has never previously happened in the sport.

Zack Minasian has overseen the Giants' pro scouting department since 2022. He was hired by former president of baseball operations Farhan Zaidi.

Previously, Minasian spent 14 seasons in the Milwaukee Brewers' front office, working as a special advisor in baseball operations and the team's director of professional scouting. When Milwaukee tabbed him to oversee pro scouting, he was the youngest to hold that position in MLB, at 27 years old.

During his tenure with the Brewers, the team made three playoff appearances and won a franchise-record 96 games in 2011. Minasian played a part in several of the team's key acquisitions, including CC Sabathia, Zack Greinke, Carlos Gomez, Josh Hader and Jean Segura.

Baseball is the family business for the Minasian clan. Zack was a batboy and clubhouse attendant under his father, Zack Sr., the longtime clubhouse manager for the Texas Rangers. Third brother, Calvin, works for the Atlanta Braves as the director of equipment and clubhouse services. Zack is also the godson of famed Los Angeles Dodgers manager Tommy Lasorda.
