MacIntyre made a glove save off the Senators’ final shooter Cole Schneider as the Marlies defeated Binghamton for the first time in four meetings this season, including a 4-2 loss on Saturday.
Greg Scott’s goal late in the second period for Toronto (29-19-6) forced overtime.
Dustin Gazley had the regulation goal for Binghamton (33-17-6).
Binghamton jumped in front at 4:24 of the first when Jean-Gabriel Pageau found Gazley alone. The winger had time to wait and pick his spot before going high above MacIntyre’s left shoulder.
Toronto tied it at 16:58 of the second when Scott came into the slot, snapped a shot through traffic and past Senators goalie Nathan Lawson.
It looked as though Carter Ashton deflected the puck in, but a review showed Scott’s shot went untouched for his fourth goal of the season.
After being outshout 20-10 through two periods, the Senators came on strong in the third period but MacIntyre, who signed with the Marlies in February, made 13 saves in the period to preserve the tie.
Lawson made 27 in regulation for the Senators.
