As you’d expect from the team with the most losses in the majors, the shortcoming of the pitching staff outweighed its strengths by a significant margin. It lacked depth and was often forced to use less than desirable options. In the end, the staff ranked 20th in the majors by fWAR, 21st by strikeouts per nine innings, and 27th by earned run average.
True, the strength of the Tigers rebuild has always been their impressive group of pitching prospects. Help is on the way, but unfortunately, the failure rate among even the best minor league pitchers is well-documented.
