San Diego Padres infielder Tucupita Marcano is under investigation by Major League Baseball for allegedly betting on baseball and could be subject to a lifetime ban, according to a person familiar with the probe.

MLB is looking into allegations Marcano bet on games involving the Pittsburgh Pirates while on the team’s injured list last season, according to the person who spoke to The Associated Press on condition of anonymity because the investigation is ongoing.

Marcano could be the second pro athlete banned for life over sports betting this year after the NBA punished Toronto Raptors player Jontay Porter in April following a league probe that found he disclosed confidential information to sports bettors and wagered on games.
