Scott, 35, spent the last two seasons with the Rays, struggling with injuries en route to a .235 average with 23 home runs and 95 RBIs in 187 games.
In nine Major League seasons, Scott has a .258 average with 135 home runs and 436 RBIs in stints with the Astros, Orioles and Rays.
Scott earned $7.75 million in his two seasons with Tampa Bay. He will make a $250,000 base salary in addition to a $50,000 signing bonus.
While he's excited about the adventure of playing in Korea, he expressed disappointment to be leaving the United States.
"Yeah, this is my home and this is where I want to play, but the last three years have been difficult for me," said Scott, who had right-shoulder surgery before joining the Rays in 2012. "Some of it was due to injury. Some of it was due to other things. But I'm thankful for this opportunity and I think it's going to be a great opportunity for me."
Scott played in a total of 16 games in the field the past two seasons, so he is looking forward to displaying his defensive skills in Korea.
"I think it will be good to play in the field every day," Scott said. "I think that will help me. It looks good for the future."
