The Major League Baseball Players Association is releasing the following statement on behalf of Marlon Byrd.

"I made an inexcusable mistake. Several years ago, I had surgery for a condition that was private and unrelated to baseball. Last winter, I suffered a recurrence of that condition and I was provided with a medication that resulted in my positive test. Although that medication is on the banned list, I absolutely did not use it for performance enhancement reasons.

"I am mortified by my carelessness, and I apologize to everyone who loves this game as I do. I will serve my suspension, continue to work hard and hope that I am given an opportunity to help a club win later this season."
