Nori Aoki will not return to the Giants in 2016.
The free agent outfielder agreed to a two-year deal with the Mariners, according to Jon Heyman of CBS Sports.
A month ago, the Giants declined their $5.5 million option on Aoki, opting instead to pay a $700,000 buyout.
“It’s just timing," Giants GM Bobby Evans explained at the time. "We’re going to keep an open dialogue with (Aoki) and just see what happens over the course of the winter and our attempts to address a number of different things ... it’ll have to be something we address more up the line...
"... To pre-determine left field today is just premature."
Over 93 games in orange and black, Aoki hit .287 with five home runs and 26 RBI.
He stole 14 bases and walked 30 times.
"He (Aoki) was a significant contributor, particularly in the first half," Evans said. "He was virtually an All-Star, or very close to it. He certainly was a big part of igniting our offense early in the season."
Aoki's deal is reportedly one year, plus an option in 2017.
The Giants are considered one of two finalists for free-agent pitcher Zack Greinke.
