The Brewers are getting right-handers Daniel Missaki, Carlos Herrera and Freddy Peralta in the trade announced at the winter meetings.
Milwaukee picked up the $8 million option for 2016 on Lind’s contract last month, but did so with the expectation that general manager David Stearns would trade him as part of the organization’s rebuilding process.
The Mariners have been looking for a first baseman because general manager Jerry Dipoto already dealt Mark Trumbo and Logan Morrison.
The 32-year-old Lind batted .277 with 20 homers and 87 RBIs in 149 games during his only season with the Brewers. He hit .291 against righties but only .221 vs. lefties last year.
He is a .274 hitter in 10 big league seasons with 166 homers and 606 RBIs for Toronto (2006-14) and Milwaukee.
Mariners new manager Scott Servais hopes to have the ability to rest Lind against left-handers on occasion, but he isn't too concerned about the sharp difference in Lind's success against right-handers as opposed to lefties.
"I would think somewhere else on our roster there would be a right-handed hitting first baseman to match up with him," Servais said. "If not, he'll get plenty of opportunities to play. Adam Lind is a good player, and that's why we acquired him, and we gave up good players to get him."
This was the third trade for the Mariners this week at the Gaylord Opryland Resort and Convention Center. They previously acquired pitcher Dave Miley from Boston and reliever Evan Scribner from Oakland.
Dealing Lind leaves Ryan Braun as the only Brewers player under contract beyond 2017.
Missaki, 19, went 1-2 with a 3.41 ERA in six starts at Class A Clinton in 2015. His season was cut short in May when he had Tommy John surgery.
Born in Japan and raised in Brazil, Missaki played for Brazil in the 2013 World Baseball Classic, appearing in one game. At 16 years old, he was the youngest player in the tournament.
The 18-year-old Herrera went 4-2 with a 3.26 ERA in the Dominican Summer League.
Peralta, 19, went 2-3 with a 4.11 ERA in 11 games -- nine starts with the Rookie Arizona Mariners in 2015.
