NEW YORK — Pittsburgh Pirates left-hander Nik Turley has been suspended for 80 games without pay after testing positive for a performance-enhancing substance.

The commissioner’s office said Saturday that Turley tested positive for Ipamorelin. The suspension will start at the beginning of the regular season.

The 28-year-old Turley made his major league debut last year for Minnesota, going 0-2 with an 11.21 earned-run average in 10 appearances. Pittsburgh claimed him off waivers in November.
