There are a lot of big name pitching prospects in the Chicago White Sox farm system, especially when it comes to left-handers. The White Sox seem to know a thing or two about left-handed pitching. The 24-year-old lefty got his first taste of Double-A just a few weeks into the minor league season. I’m really excited about what he could bring to the White Sox rebuild. This February, the White Sox signed him to a minor league contract.
