The one thing to keep in mind when it comes to Palmeiro and a serious comeback is that he was always one of the purest hitters in the game, even when his power stroke mysteriously developed in the height of the PED era.
Palmeiro, who played for the Cubs, Rangers and Orioles over his 20-year career, retired in September 2005 after serving a 10-game suspension for testing positive for steroids.
"I've taken care of myself really well", he said.
Palmiero walked away from the game quietly in September 2005 after he was suspended for testing positive for steroids, going down in history as the first Major League Baseball player to be suspended for doping. I've been working out for years.
"Let me start by telling you this: I have never used steroids, period", Palmeiro said. "Maybe 12 years later, I can prove to the whole world that I didn't need anything to have a good career", he says. Palmeiro is 53 years old.
To this day, Palmeiro has maintained that he's never used performance enhancing drugs.
Julio Franco, who last played in the major leagues for the Atlanta Braves in 2007 at 49, tried a comeback in 2014 for the Fort Worth Cats of the independent United League Baseball.
Baltimore general manager Dan Duquette did not entirely dismiss the notion of giving Palmeiro a shot. The 22-year-old first baseman hit.253 with 13 home runs and 77 RBIs while playing for the team's Class-A affiliate, Delmarva, last season.
"If I go to spring training with a legitimate chance to make the team, I won't have to go to the minors", he said.
As of right now, Minoso, a White Sox legend, is the fourth-oldest player to appear in a Major League Baseball game.
