On Wednesday night, the Chicago White Sox had a very high-end pitching prospect in Michael Kopech headed to the mound to take on the Detroit Tigers. Kopech appeared destined to headline a talented young Sox rotation in the years ahead. With Carlos Rodon, Reynaldo Lopez, Lucas Giolito, and several more good young arms in the farm system, it wasn’t out of the question that the Sox could put together a dangerous young team as early as 2019. A few hours later, and Kopech was instead destined for Tommy John surgery, and won’t be back on the mound until 2020 if all goes well.
