The Pirates signed the 33-year-old right-hander last year, knowing at the time that he would be rehabbing for most of the 2019 season. His contract included an option for 2020. He debuted in the GCL on August 6th, and made two appearances with Morgantown, then one for Altoona, before missing the final three weeks of the season.
Koehler was a non-roster invite this year, but he didn’t pitch in any games this spring. He pitched six years in the majors, and posted a 4.39 ERA over 784.1 innings, spent mostly with the Miami Marlins.
