Mark McGwire is finally confessing ... he used steroids. Duh.
In a carefully written, blame-shifting statement, McGwire said, "I wish I had never touched steroids ... It was foolish and it was a mistake. I truly apologize. Looking back, I wish I had never played during the steroid era."
McGwire said he took steroids during the 1998 season when he hit 70 home runs, then a record.
