After a dramatic finish to the regular season that included a no-hitter on the final day and a tie that will force a special elimination game Monday night, Major League Baseball is set to start its playoffs.

Research intended to help people with muscle-wasting diseases could be about to launch a new era in performance-enhancing drugs.

The research has produced several muscle-building drugs now being tested in people with medical problems, including muscular dystrophy, cancer and kidney disease. The drugs all work by blocking a substance called myostatin that the body normally produces to keep muscles from getting too big.

One chapter of the Biogenesis scandal closed yesterday with MLB dropping the hammer on 13 players who bought performance-enhancing drugs at the Coral Gables clinic. But many other questions remain, including whether clinic owner Tony Bosch will ever face criminal charges and how he managed to peddle illegal drugs without a medical license for so many years.

Here's a better look and listen to what it was like Monday night in Chicago when New York Yankees third baseman Alex Rodriguez returned to the lineup on the same day he was hit with a 211-game suspension for allegedly using performance-enhancing substances (he can play while he appeals that punishment).

New York Yankees' slugger Alex Rodriguez, one of baseball's brightest stars and its highest-paid player, will be suspended through the 2014 regular season because he violated parts of baseball's Joint Drug Prevention and Treatment Program, the league said today.

According to several news reports, Major League Baseball has given the players union a list of those facing suspensions because of doping.

In truth, this is another pit stop in the long march toward what is rumored to be the suspension of some of baseball's A-listers. Of course, the biggest target is rumored to be Alex Rodriguez.

Doping in sports is back in the news and you don't need to be a sports fan to have heard about it. The PBS Newshour devoted a segment to the recent disclosure that Tyson Gay, America's top sprinter and self-declared Mr. Clean, had failed a drug test.
