LHP Wei-Yin Chen, Miami Marlins
The often-penny-pinching Marlins surprised the industry when they pounced on Chen for a five-year, $80 million deal (with a two-year opt-out) after 2015, a contract the Orioles had no interest in matching.
The gamble has backfired big time on the Marlins. Chen stumbled (5-5 with a 4.96 ERA in 22 starts) in his debut season for Miami in 2016, and this year he made just five starts before landing on the disabled list with left arm fatigue. He’s been on the shelf ever since with no timetable for his return, and nobody seems entirely clear about the nature or severity of his injury.
