The Westboro Baptist Church has announced plans to picket Games 3 and 4 of the World Series at Busch Stadium this weekend.
The Kansas-based church has been banned in some states from protesting near the funerals of servicemen and women and is known for disrupting services of private citizens as well.
The church is calling for protesters to demonstrate against "the worthless strutting peacocks of these two baseball teams...glorifying themselves instead of God".
St. Louis city police have said security downtown will be heightened for the Fall Classic.
Police Chief Sam Dotson met Monday with officials from the FBI, ATF, Homeland Security, and the Missouri Highway Patrol to discuss extra safety measures.
