Sabathia announced plans to enter treatment for alcohol abuse on Monday, via an E! News report on Monday. In a statement to fans, Sabathia wrote, "Today I am checking myself into an alcohol rehabilitation center to receive the professional care and assistance needed to treat my disease."

"I love baseball and I love my teammates like brothers, and I am also fully aware that I am leaving at a time when we should all be coming together for one last push toward the World Series," Sabathia continued. "It hurts me deeply to do this now, but I owe it to myself and to my family to get myself right. I want to take control of my disease, and I want to be a better man, father and player."

Also on Twitter this week, Rodriguez spoke of the "brotherhood" of his team.
