Miami Marlins starting pitcher Wei-Yin Chen struggled against the Nationals on Sunday, pitching 4 1/3 inning and allowing seven earned runs. Chen dropped to 2-6 on the year and holds a 6.14 ERA over 14 starts. The Marlins signed Chen to a five year/$80 million contract in 2016 and he is now on the books until 2022. He was a bad investment then and he's an even worse investment in fantasy leagues now. He needs to be left on the waiver wire.
