GLENDALE, Ariz. -- When Michael Kopech started throwing again after right knee surgery, he felt a sense of relief.
It was a real issue that prevented him from being himself for much of last season with the Chicago White Sox.
"Absolutely. There's a little bit of relief knowing that I wasn't just trying hard and it not coming out last year," Kopech said. "There was something that I had to fight through, which take it with a grain of salt. I'm going to battle through everything that I have to battle though. But ultimately, I want to be as healthy as I can and I'm on track to do that now.
