Frank Thomas confirmed he is officially retired on Thursday.

"No, I'm done, I'm done," said Thomas, who figures to talk more about his decision during a press conference Friday at U.S. Cellular Field. "I've had a great career. I've had 20 Spring Trainings, 21 Spring Trainings, and I'm happy where I'm at right now.

"Life goes on. I have a 15-month old baby, and I've spent a lot of time with my [four] kids during this last year and a half. I caught up with the time that I missed away from them. I'm really happy. I'm taking care of myself and I feel good."

Thomas last played during the 2008 season.

RealGM Note: Thomas ranks 15th all-time in career OPS with a mark of .974 and 18th in homers with 521.
