Castro was questioned by Chicago police in mid-January after he was accused of sexually assaulting a woman on Sept. 29, the night after the regular season ended. No criminal charges have been filed against Castro, 21, and there have been no new developments since the shortstop spoke to the police.
Epstein said on Saturday that the club has invited people from Sport in Society of Northeastern University to conduct seminars this spring for the players, in hopes of helping them make the right decisions off the field. Sport in Society covers such topics as leadership, diversity and inclusion, violence prevention and community service.
The baseball operations staff created a "Cubs' way" manual this week to make sure that they coach everyone in the system the same way. But Epstein said that there's more involved.
"The Cubs' way means high standards off the field," Epstein said.
In his first full Major League season in 2011, Castro led the National League in hits and was named to the All-Star team.
