Los Angeles –

San Diego Padres infielder Tucupita Marcano has been banned for life from Major League Baseball for betting on games, the league announced on Tuesday.

Michael Kelly, a pitcher for the Oakland Athletics, and three minor league players were also suspended for a year for gambling on baseball games, MLB said.

“The strict enforcement of Major League Baseball’s rules and policies governing gambling conduct is a critical component of upholding our most important priority: protecting the integrity of our games for the fans,” MLB Commissioner Robert Manfred said in a statement.
