Leake's agent Danny Horwitz said in a statement, per USA Today: "During this global pandemic, Mike had many discussions about playing this season. They took countless factors into consideration, many of which are personal to him and his family. After thorough consideration, he has chosen to opt out of playing in 2020. This was not an easy decision for Mike. He wishes the best of luck and health for his Diamondbacks teammates this season and he's looking forward to 2021."
