Swayman allowed one goal on 21 shots during Tuesday's 5-1 preseason win over the Flyers.
After Michael DiPietro played in Sunday's preseason opener, Swayman got the starting nod for Tuesday's exhibition contest and played the entire game. The Bruins close out the preseason with a back-to-back set Thursday in Philadelphia and Friday in Washington. Swayman will probably make one more appearance before serving as Boston's starting netminder once the regular season begins.
