Former MLB star Rafael Palmeiro, who left the game in disgrace after testing positive for steroids back in 2005, tells Ken Rosenthal of The Athletic that he is seriously contemplating an effort to return to the majors. Of course, there are quite a few barriers for the left-handed-hitting first baseman, who is a dozen years removed from his playing days and is now 53 years of age.

It’s frankly hard to imagine how this concept could come to fruition. Any player of his age would make for an unlikely big leaguer: in the modern era, only Minnie Minoso has appeared past fifty years of age, and that was a promotional/honorary stunt. The ageless Julio Franco played at the relatively tender age of 49, though he wasn’t able to produce.

Palmeiro’s highly controversial past adds yet more obstacles; notably, he still has not admitted to intentionally using steroids to aid his performance, though he does acknowledge a positive test.
