Jack McKeon’s baseball days begin in a pew. At 8 on Tuesday morning, the Florida Marlins’ manager attended Mass at St. Patrick’s Cathedral, less than 12 hours after his team beat the Mets on a 10th-inning grand slam. Such games are testament to his faith in the saint he prays to every game during the national anthem.

“A good night for St. Thérèse,” he said, sitting in the lounge of a Midtown Manhattan hotel.

In each major league city, McKeon has a favorite, or at least a convenient, Roman Catholic church. If he does not know their names, he can describe them or tell you how to get there. In Cincinnati, it’s SS. Peter and Paul. In Chicago, Mass is at Holy Name Cathedral. In Philadelphia, he goes to what he calls “the oldest church in the U.S.” When the Marlins stayed at a hotel on the East Side of Manhattan, he followed these directions: “Walk out the door, take a left, walk 30 yards, and take a right, where the homeless hang out.”

For each of the regular churches in his personal directory, he learns the Mass schedule.

“At St. Patrick’s it’s 7, 7:30, 8, noon and 12:30,” he said. “They’re very flexible.”

Mornings at church “give me energy,” he said. “You’re free. You feel good.” His daily ritual is part of a baseball routine that is now in its 62nd year, stretching back to D League ball in Greenville, Ala.
