BOSTON -- Security was tight at Fenway Park, where the Red Sox are back on the field for the first time since Monday’s bombing at the Boston Marathon.

The Red Sox were scheduled to play the Kansas City Royals at 1:10 p.m. Across town, the Bruins were scheduled to play the Pittsburgh Penguins at the TD Garden at 12:30.

A SWAT team member with a German shepherd stood guard at the doorway to the tunnel leading to visitors’ dugout about 2½ hours before game time. A man in military fatigues checked all of the Royals’ lockers and the many cracks in the ceiling tiles with a flashlight.

Outside, fans milled around, waiting for the gates to open. Several of them were wearing Boston Marathon jackets dating back as much as a decade.
