A gas explosion at the Lake Elsinore minor league baseball stadium sent two people to the hospital on Friday afternoon.

Authorities received reports of the explosion at Lake Elsinore Diamond Stadium, or Storm Stadium, around 4:21 p.m., according to the Riverside County Fire Department and Cal Fire.

Two people were burned and were transported to a local hospital with moderate injuries.

The stadium is home to the Lake Elsinore Storm, a Single-A affiliate of the San Diego Padres.

The stadium was evacuated and the Storm’s game against the Inland Empire 66ers on Friday night was postponed.

“Due to an incident at the stadium, today and tomorrow’s game will be postponed until further notice,” the team announced on Twitter.

The cause of the explosion remains under investigation. Local gas companies were notified and responded to the scene.

It’s unclear whether any fans were inside the stadium when the explosion occurred.
