Pirates left-hander Nik Turley has been suspended for 80 games without pay after testing positive for a performance-enhancing substance called Ipamorelin, the league announced Saturday. Turley will begin his suspension at the start of the 2018 season.

The 28-year-old lefty is coming off of his first season in the majors, one in which he never quite managed to find his footing. He debuted with the Twins in the summer of 2017 and bounced back and forth between the majors and Triple-A, eventually finishing the year with an unsightly 11.21 ERA, 4.1 BB/9 and 6.6 SO/9 in 17 2/3 innings.
