The new wave of legal gambling is prompting Major League Baseball to closely monitor starting lineups.
Ballclubs this season must notify the commissioner's office of their lineups before they are announced at stadiums. The decision comes in response to the Supreme Court ruling last spring that has led to more widespread legal gambling.
Through last season, clubs announced lineups as they wanted, some by posting in clubhouses, others in email to media, on Twitter or their websites.
MLB will confirm receipt and then distribute the information to its data and business partners. The team may announce the lineup either when it receives confirmation of receipt by MLB or 15 minutes after sending the lineups to MLB.
The commissioner's office says its new approach "mirrors those of international sports leagues in more developed betting markets."
