Mr. Schmoke said at his weekly news briefing that he, Gov. William Donald Schaefer, Oriole owner Peter G. Angelos, city and state police officials and Secret Service agents met yesterday at the governor's office to talk about the pope's visit here.
"We discussed the pleasant possibilities of the complication that could arise, which is that the date for the Mass is also the date for the second game of the World Series at the home of the American League team," the mayor said.
"We are going to plan as if both will occur."
Mr. Schmoke said the time and other details of the papal Mass have not been set, but he said they would plan around the possible start of an evening World Series game.
Officials of the Orioles and the Baltimore Archdiocese could not immediately be reached for comment.
Mr. Schmoke said plans also call for the pope to visit one of the city's Roman Catholic cathedrals and see one of the social service programs run by the church here.
"The archdiocese is still working on this," the mayor said. "The exact order, the exact time, we still have to work on. All the plans that we put together right now are still subject to review by the Vatican," he added.
