The Tigers optioned left-hander Robbie Ray to Triple-A Toledo after today’s start against the Rangers and Chris Iott of MLive.com hears that the team will call up right-handed reliever Corey Knebel for Friday’s game.

It’s been a rapid rise for Knebel, who was drafted No. 39 overall by the Tigers in last June’s First-Year Player Draft. The 22-year-old has posted a 0.90 ERA and 68/19 K/BB ratio over his first 50 innings in pro ball. This includes 11 appearances in Double-A this year and three scoreless appearances after a recent promotion to Triple-A. He’ll be the second player from the 2013 draft class to reach the majors, as the Indians called up fourth-rounder Kyle Crockett for a brief stint last week.
