Brewers make Astros' David Stearns, 30, MLB's youngest GM

The Milwaukee Brewers have hired David Stearns, assistant general manager of the Houston Astros for the past three seasons, as their new general manager, a baseball source confirmed to ESPN.com on Sunday.

Stearns, 30, will replace Doug Melvin, who is transitioning to an advisory role with the Brewers after serving as the team's GM since 2002.

Stearns, a 2007 Harvard University graduate, worked for the commissioner's office from 2008 to 2011 and spent two years as director of baseball operations for the Cleveland Indians before joining the Astros as the top assistant to GM Jeff Luhnow.

His duties in Houston included player evaluations and contract negotiations, and he also helped oversee the Astros' scouting, player development and analytics departments.

Stearns, who is expected to be named to his new post Monday, will be the youngest current general manager in baseball and is one year younger than Milwaukee's most high-profile player, outfielder Ryan Braun.

The Brewers, who faded badly down the stretch last year to miss out on a postseason berth, are 63-86 this season and last in the NL Central with two weeks to play.

Stearns' hiring in Milwaukee leaves the Boston Red Sox, Philadelphia Phillies, Los Angeles Angels and Seattle Mariners as MLB teams still in the market for a GM.

FoxSports.com earlier reported Stearns' imminent hiring by the Brewers.
