Marmol's case was sent to a higher court in the Dominican Republic Friday, but Epstein told the Chicago Tribune he expected the matter to be settled quickly.
"We take any accusation of this nature seriously," Epstein said. "All the information we could gather supports Carlos' contention that he is innocent of any wrongdoing. We expect this matter to be behind him soon."
A 24-year-old woman accused Marmol of assaulting her in October. The Tribune said police had apparently not formally charged Marmol but the complaint was moved up the ladder Friday to the Supreme Court of Justice.
Marmol's lawyer, Nelson Pimentel, told the Tribune he expected Marmol to report to spring training in Arizona Monday, despite a move by the alleged victim's lawyers to bar him from leaving the Dominican Republic.
"Carlos will be OK and in time at training camp," Pimentel said in an email.
