The Dodgers also announced they named former San Diego Padres general manager Josh Byrnes their senior vice president of baseball operations.
The 37-year-old Zaidi, an MIT-educated baseball analyst, worked last season as the A’s assistant general manager and director of baseball operations. He had been with Oakland since 2004.
Last month, the Dodgers named former Tampa Bay Rays executive Andrew Friedman their president of baseball operations. At the same time, they announced that Ned Colletti, the Dodgers' general manager from 2006-2014, would be shifted to a senior advisor position in the front office.
In an offseason profile of Zaidi, A's director of player personnel Billy Owens told Susan Slusser of the San Francisco Chronicle that Zaidi had a future as a general manager.
"He's engaging, he's able to look at baseball from every angle, consider every element, and he has great leadership skills," Owens said. "He should be an emerging GM candidate for sure."
