Tuesday game's between the Chicago White Sox and Baltimore Orioles has been postponed, the team announced.
The first game of a three-game-series on Monday night was also postponed because of safety concerns after rioting broke out near the stadium following the funeral of Freddie Gray, a 25-year-old who died on April 19 after suffering a severe spinal injury while in police custody. Six Baltimore police officers have been suspended pending a probe into Gray's death.
Baltimore mayor Stephanie Rawlings-Blake issued a citywide curfew from 10 p.m.- 5 a.m. ET for the remainder of the week. The Orioles' homestand lasts through Sunday with the completion of their series against the Tampa Bay Rays.
During the unrest, at least 15 police officers were injured when looters stole from stores, threw rocks and bricks at Baltimore police throughout the night, and set multiple fires.
Protesters have clashed with police since last weekend.
On Saturday, Baltimore police officials asked fans at Camden Yards for a game to remain in the park due to protests in the area that turned violent earlier in the day. It was not until after the game ended that the gates were re-opened and fans were allowed to exit the ballpark.
Major League Baseball has moved games before due to civil unrest in cities. The Los Angeles Dodgers had to postpone four games in the wake of the Rodney King verdict in 1992.
The Baltimore Ravens also canceled Thursday night's draft party because of the curfew.
