Harrington was the 36th overall pick in the 2022 MLB Draft and a former top prospect in the Pirates’ system. Heading into last year, he was the 80th-ranked prospect in all of baseball, according to MLB Pipeline, and the third-ranked prospect for Pittsburgh, ahead of Braxton Ashcraft and Mike Burrows. However, the command specialist struggled at the upper levels of the minors, posting a 5.34 ERA in 96 innings at Triple-A last year and a 6.52 ERA in 58 innings this season. He has since moved into a bulk relief role, which is likely how he will be used in Pittsburgh now.
