NEW YORK — Mark McGwire finally came clean, admitting he used steroids when he broke baseball’s home run record in 1998.

McGwire said in a statement sent to The Associated Press on Monday that he used steroids on and off for nearly a decade.

“It’s very emotional, it’s telling family members, friends and coaches, you know, it’s former teammates to try to get ahold of, you know, that I’m coming clean and being honest,” he said during a 20-minute telephone interview, his voice repeatedly cracking. “It’s the first time they’ve ever heard me, you know, talk about this. I hid it from everybody.”

McGwire said he also used human growth hormone, and he didn’t know if his use of performance-enhancing drugs contributed to some of the injuries that led to his retirement, at age 38, in 2001.

“That’s a good question,” he said.

He repeatedly expressed regret for his decision to use steroids, which he said was “foolish” and caused by his desire to overcome injuries, get back on the field and prove he was worth his multimillion salary.
