After a pair of postponements caused by rioting in Baltimore, the Orioles and Chicago White Sox will play Wednesday at Camden Yards in what is believed to be the first game without fans in Major League Baseball’s history.

Because of the unsettled environment in Baltimore, where rioters burned a drug store and set police cars ablaze on Monday night, officials moved the game up five hours from its original 7:05 p.m. starting time and closed it to the public.

“It’s all about what’s best for the city and the safety of our people,” Orioles manager Buck Showalter said in a telephone interview with the Associated Press. “The last thing you want to do is put the fans in harm’s way. You have to err on the side of safety.”

Schools were closed Tuesday and the mayor imposed a 10 p.m.-to-5 a.m. curfew. The announcement of the unique closed-doors game came late Tuesday afternoon, after the Orioles postponed games against Chicago on Monday and Tuesday.

The Baseball Hall of Fame and John Thorn, MLB’s official historian, said they did not think there ever had been a closed-doors big league game, although there have been instances in the minor leagues.

Since 1987, the lowest attendance has been 746 when the White Sox hosted Toronto at Comiskey Park on April 9, 1997, according to STATS. The New York Yankees’ home game against the White Sox on Sept. 22, 1966, has a listed attendance of 413.

Thorn said the lowest attendance for a major league game appears to be six when Worcester hosted Troy in a National League game on Sept. 28, 1882.

Monday’s game was postponed around 40 minutes before the scheduled 7:05 p.m. start. The decision came after riots broke out following the funeral of Freddie Gray, who died April 19 of spinal cord and other injuries sustained while in police custody.

Tuesday’s game, also scheduled for 7:05, was called off shortly after 11 a.m.

Also Tuesday, the uneasy situation also caused the Baltimore Ravens to cancel an NFL draft party for fans at M&T Bank Stadium on Thursday night.

The team said the decision was made “out of respect to the curfew.”
