The Yucatan state prosecutors’ office said Tuesday that Arozarena was detained “for problems relating to his ex-partner.”
It was not clear if he was formally charged with any crime. Mexican law allows a two-day period for prosecutors to decide whether to bring charges. Normally suspects are held in jail pending that decision.
Local media reported that Arozarena married a Colombian woman earlier this month in Merida, the Yucatan state capital.
He hit .377 with 10 homers and 14 RBIs in 20 postseason games for Tampa Bay.
