In what should stand as the least surprising move of the offseason, left-hander Wei-Yin Chen formally decided this weekend to remain with the Miami Marlins. The move was a technicality. Chen signed a five-year, $80 million deal with the Marlins in January 2016. That included an opt-out clause after two seasons, meaning Chen had to choose that, yes, he would like the final $65 million for the next three years. Chen opting to stay in South Florida was first reported by the Miami Herald Sunday. Chen is set to make $10 million in 2018, $20 million in 2019, and $22 million in 2020. The Marlins also owe him his two-installment signing bonus in the coming months, according to Cot’s Baseball Contracts: $5 million on Nov. 30 and $8 million on June 30. The investment has been a poor one for the Marlins so far. Chen has missed about half of the last two seasons with elbow issues related to a partially torn ulnar collateral ligament in his left elbow.
