The Major League Baseball Players Association (MLBPA), which represents Major League baseball players, sued sports agent William Arroyo of Rimas Sports, where codefendants Noah Assad and Jonathan Miranda are senior executives, to confirm an arbitral award.

In its suit, the players’ union asserted issuance of a notice of discipline for defendants’ violation of its regulations, revocation of Arroyo’s certification, and denial of certification to Assad and Miranda.
