The Major League Baseball Players Association will review the safety and security protocols of all teams and stadiums in light of recent events in Chicago and Denver.

In a span of four days, a shooting likely happened inside Guaranteed Rate Field and two fans ran at Ronald Acuna, Jr. on the field in Colorado.

"Following security incidents, including those on field, our director of security is in immediate contact with MLB security and local authorities where appropriate," the MLBPA said in its statement. "In addition to our security experts, our PA player services staff is in daily contact with players -- providing updates and any relevant information.

"While the details of the recent incidents in Chicago and Denver are still under investigation, we will be reviewing the club and stadium protocols currently in place, as we do throughout every season, to mitigate the possibility of similar future incidents."
