The Yucatan state prosecutors’ office confirmed Tuesday that Arozarena was detained “for problems relating to his ex-partner.”
He has not been formally charged yet. Mexican law allows a two-day period for prosecutors to decide whether to bring charges. Normally suspects are held in jail pending that decision.
Major League Baseball is looking into the matter, a source told ESPN’s Jeff Passan
Arozarena has made no public comment, and it was not clear whether he had a lawyer yet.
Arozarena hit .377 with 10 homers and 14 RBIs in 20 postseason games for Tampa Bay. He was named MVP of the AL Championship Series.
