NEW YORK — The baseball players’ association says any suspensions resulting from the sport’s latest drug investigation likely won’t be served until next year if the discipline is challenged before an arbitrator.

Union head Michael Weiner expects Major League Baseball will notify the union of its plans for penalties in the next month, and the association will maintain any discipline should not be announced until after a grievance hearing, and then only if arbitrator Fredric Horowitz upholds a ban.

“We’re going to have a discussion with them. That discussion will include whether or not names of suspended players will be announced publicly,” Weiner said Tuesday during a meeting with the Baseball Writers’ Association of America.

Former MVPs Alex Rodriguez and Ryan Braun are among the more than a dozen players under investigation for ties to Biogenesis, a closed anti-aging clinic in Florida linked with the distribution of performance-enhancing drugs. MLB officials have been interviewing players, who have been represented by the union and their own lawyers.

A provision in baseball’s drug agreement says discipline for first offenders can be announced before a hearing if the penalty results from an allegation that became public other than through MLB or a team. Miami New Times published allegations in January, but the union could argue that a penalty results from evidence baseball has gathered rather than the newspaper account.
