The fallout from Mathew Bowyer’s alleged illegal bookmaking operation isn’t quite over for MLB.

The league said Monday it has opened an official investigation into gambling allegations surrounding David Fletcher, a former Angels player and close friend of Shohei Ohtani who is now in the minor leagues, according to ESPN.

ESPN reported Friday that Fletcher and his close friend Colby Schultz, another minor leaguer, had placed bets with Bowyer, the same bookmaker used by Ohtani’s former interpreter Ippei Mizuhara. Some of Schultz’s bets included Angels games in which Fletcher played, while Fletcher bet on sports excluding baseball, ESPN reported.
