Law experts said the case might be hard for Pujols to win.
“In order to succeed in his case, he will have the burden of proving the allegations were materially false,” said Amy Ginensky, a media attorney in Philadelphia. Clark, meanwhile, doesn’t have to prove his claim is true.
“My lawyers have told me that the upcoming legal fight will not be an easy one, and that in cases like this even a liar can sometimes be protected under the law,” said Pujols, who denied using performance-enhancing substances. “But as a man of faith, I have never shied away from standing up for the truth, and I believe that the principles at stake are too important to sit back and do nothing.”
Clark said Pujols' trainer, Chris Mihlfeld, told him he injected Pujols with performance-enhancing drugs in 2000.
