Joe Tacopina, attorney for Alex Rodriguez, responded on Happening Now today to the explosive allegations against the New York Yankees third baseman.

On "60 Minutes" Sunday, the lead witness in MLB's case against Rodriguez claimed that the slugger paid him $12,000 per month in cash for performance-enhancing drugs.

Anthony Bosch, the founder of the Miami-based Biogenesis clinic, said Rodriguez often took testosterone orally right before games, in the form of a small "gummy." He also said he personally injected Rodriguez with steroids.

Rodriguez has maintained that Bosch's claims are false, denying any use of performance-enhancing drugs. Over the weekend, his 211-game suspension was reduced to 162 games, equivalent to the entire 2014 season.

Tacopina was in federal court this morning seeking an injunction against the ban.

In the interview with Jenna Lee, Tacopina lashed out at MLB Commissioner Bud Selig's handling of the matter, questioning why Rodriguez was not given a 50-game suspension.

Tacopina emphasized that this is the first time MLB has gone after a player without a positive test to prove steroid use.

He slammed Bosch's allegations as "fantasy," questioning how Bosch can be taken seriously given the deal he struck with MLB.
