BOSTON (AP) -- The Red Sox and Bruins postponed their games Friday as authorities searched for a suspect in the Boston Marathon bombings, virtually shutting the city down.

The teams announced about four hours before their night games were scheduled to start that they were scratched.

Police identified two suspects in Monday's explosions that killed three people and wounded more than 180. One man was killed during a shootout with police and the other was being sought in a massive police effort that dragged through the day.

Authorities in Boston suspended all mass transit, used by many fans to get to games, and told people in throughout Boston and some of its suburbs to stay inside for much of Friday as the hunt for Suspect No. 2 went on. Trains were finally allowed to run again after 6 p.m.

No makeup date was announced for the opener of the Red Sox three-game series against the Kansas City Royals scheduled at Fenway Park.

Saturday's game, set to start at 1:35 p.m., was still on.

The NHL game at TD Garden between the Bruins and the Pittsburgh Penguins, two of the top four teams in the Eastern Conference, will be played Saturday at 12:30 p.m.

Capacity at Fenway Park, about one mile from the finish line, is 37,493 for night games. Capacity at TD Garden is 17,565.

With fans advised to stay home and police devoted to the manhunt, the decision to postpone was easy.

The Bruins also announced that the sale of playoff tickets, scheduled to start at 11 a.m. Friday, has been put off until 11 a.m. Monday.

The New England Patriots postponed for the second time a news conference with director of player personnel Nick Caserio about next week's NFL draft. The news conference originally had been scheduled for Tuesday but was postponed after the bombings.

It has been rescheduled for Monday.
