Is Alex Rodriguez on deck for Biogenesis punishment? (Daniel Wallace / AP)

With Ryan Braun slinking off to serve his 65-game suspension from baseball, the focus now turns to the other player most frequently mentioned as a target for punishment in connection with baseball’s Biogenesis investigation: Alex Rodriguez.

A-Rod, who is presently on the disabled list with a quadriceps strain as he tries to play in the majors for the first time since he had hip surgery in January, is believed to be among a group of players who will next be punished by Major League Baseball. While the New York Yankees might prefer never to see A-Rod and his contract again, the third baseman has support from two highly esteemed Yankees.

“I don’t know what happened with Alex,” reliever Mariano Rivera said (via ESPN New York). “He is my teammate, and I have to support him 100 percent. So I don’t know, if something different happens, we need to see. The good thing about this is we are cleaning the game, and that’s the way it should be.”

There have been reports of a 100-game suspension, meriting a lengthier one than Braun received because MLB believes he interfered with the investigation, according to ESPN. It is expected that MLB will announce the rest of the Biogenesis suspensions at one time.

“I have to support him. He’s my teammate. He’s my brother. Definitely,” Rivera said. “I don’t know if he did or didn’t do it, but if it happens I can’t throw him on the street. He’s still my brother.”

Another member of the Yankees’ core four, Andy Pettitte, admitted that he used human growth hormone after he was mentioned six years ago in the Mitchell Report on drugs in baseball. Pettitte believes a player in Braun’s spot should do as he did — move forward after admitting guilt and accepting punishment.

“We’re going to back him up,” Pettitte said. “We’re his teammates. There’s no doubt. But if you did something wrong, you’re going to be punished for it. But I’ll still back him up. I’m still going to love him because I built a relationship with him. He’s a teammate of mine.”
