BOSTON — The Red Sox and Bruins were ready to return to action after a daylong, successful manhunt for a suspect in the Boston Marathon bombings brought the city, and major sports along with it, to a standstill.

The Red Sox play the Kansas City Royals on Saturday afternoon following the postponement of Friday night’s opening game of the scheduled three-game series at Fenway Park.

The Bruins face the Pittsburgh Penguins, also on Saturday afternoon, in a meeting of two of the top four teams in the Eastern Conference. The game had been postponed from Friday night. The Penguins’ scheduled home game against the Buffalo Sabres on Saturday night was rescheduled for Tuesday night.

Both the Red Sox and Bruins said on their websites that they expected their games on Saturday would be played.

Friday’s postponements came about four hours before the games were to start, after authorities told people throughout Boston and some of its suburbs to stay indoors while they searched for the suspect. Early in the evening, not long after mass transit resumed, authorities apprehended Dzhokhar Tsarnaev, the man known as Suspect No. 2 in the bombings.

Beyond the Red Sox and Bruins, the case impacted other sporting activities planned for the weekend.

Boston College canceled all home athletic events for Saturday, including the annual spring football game.

The suspension of Amtrak train service forced the New England Revolution of MLS to change plans and travel by bus Friday morning for their game against the New York Red Bulls on Saturday night at Red Bull Stadium in Harrison, N.J.
