Rose gambled on baseball while he was a player/manager. That is prohibited. I don’t think Ohtani’s interpreter gambled on baseball, but who knows? And was it Ohtani who actually was the one gambling? It all seems suspicious, but hopefully MLB will do a thorough investigation. For the record, here is the MLB rule regarding gambling. If I’m reading it incorrectly, unless he was gambling on baseball or gambling illegally, it’s not against the rules. We will see what the investigation turns up.
(d) GAMBLING.
(1) Any player, umpire, or Club or League official or employee, who shall bet any sum whatsoever upon any baseball game in connection with which the bettor has no duty to perform, shall be declared ineligible for one year.
(2) Any player, umpire, or Club or League official or employee, who shall bet any sum whatsoever upon any baseball game in connection with which the bettor has a duty to perform, shall be declared permanently ineligible.
(3) Any player, umpire, or Club or League official or employee who places bets with illegal book makers, or agents for illegal book makers, shall be subject to such penalty as the Commissioner deems appropriate in light of the facts and circumstances of the conduct. Any player, umpire, or Club or League official or employee who operates or works for an illegal bookmaking business shall be subject to a minimum of a one-year suspension by the Commissioner. For purposes of this provision, an illegal bookmaker is an individual who accepts, places or handles wagers on sporting events from members of the public as part of a gaming operation that is unlawful in the jurisdiction in which the bets are accepted.
