MLB is investigating Padres infielder Tucupita Marcano for a violation of the league’s gambling policies, which could result in a lifetime ban, The Wall Street Journal reported.

Marcano has been accused of betting on games featuring the Pirates during the 2023 season while he was on the team’s injured list. His punishment hasn’t been finalized as negotiations between the MLB Players Association and the league are ongoing. Four other minor league players could face discipline over similar gambling offenses, according to the WSJ.
