BALTIMORE | First Lady Michelle Obama will take part in the first pitch ceremony at a game between the Tampa Bay Rays and the Baltimore Orioles at Camden Yards.

Obama will be escorted Tuesday to home plate by players with the RBI program and the Boys and Girls Club, who will throw out the first pitch.

Orioles officials warn that because of increased security at the ballpark, fans should expect long lines at the gates. All fans must go through magnetometers, and all packages and containers brought into Camden Yards will be inspected.
