MLB Biogenesis Scandal: Alex Rodriguez Faces Lifetime Ban from Baseball for Using Performance Enhancing Drugs Now, to tarnished heroes on the diamond. Major league baseball expecting to suspend some of its top stars as earl as today, because of their connection to a lab that is linked to performance-enhancing drugs. Paula faris has the latest. A lot of people watching this one closely. Reporter: Abc news has learned that major league baseball plans to announce these punishments and suspensions simultaneously. It could happen at any moment. And this morning, all eyes are on the highest-paid player in the game's history. Yankees third baseman, alex rodriguez, dodged questions, as he drove off in his year $500,000 car late wednesday. The highest-paid player in baseball history is continuing to rehab stint at the yankees training facility in tampa. Hoping to get back on the field after his surgery. This morning, there's a chance he won't return this season, if ever. In what could be the biggest scandal in sports history, as many as 20 players, including rodriguez, have reportedly been implicated for using performance-enhancing drugs. And getting those drugs from the now defunct biogenesis anti-aging clinic in florida. Former league mvp, ryan braun, was the first to fall. Accepting a 65-game suspension last week. But a-rod, is now at the center. Sources tell espn, major league baseball now believes it has enough evidence of alleged doping by the star to impose a lifetime ban. If they do, they know they're going to get in an incredible fight with the union. That's something that baseball is trying to avoid. Reporter: If guilty, this would be a-rod's second offense. He famously denied doping in 2007, on '60 minutes. Have you ever used steroids, human growth hormone or any other substance? Reporter: Only to come clean to espn two years later. I wanted to prove to everyone that I was worth, you know, being one of the greatest players of all-time. Reporter: This morning, sources say these new allegations are far more serious because major league baseball reportedly believes a-rod not only continued to use performance-enhancing drugs, but that he interfered with its investigation. Now, a-rod's legal team has repeatedly said they will appeal any suspension. However, espn's "outside the lines" reporting late last night, that his reps are now negotiating a possible plea deal, which could still lead to a likely suspension. And again, amy, any moment now, this could happen. A lot of disappointed fans, everywhere. Thanks, paula.
