Erik Johnson. Does that name sound familiar to you?
He was the Chicago White Sox top pitching prospect in 2013 going 12-3 with a 1.96 ERA between Birmingham (AA) and Charlotte (AAA). That success carried over in the big leagues as he went 3-2 with a 3.25 ERA in five starts as a September call-up.
Based on that success, Johnson started the season in the majors the following year but was a complete disaster. In five starts, the big right-hander pitched just 23.1 innings with a 6.46 ERA and 18 walks and was optioned back to Charlotte.
