Arcobello found Teubert for a one-time chance just in front of the net but Teubert couldn't connect, as the puck dribbled past him and time ran out to send the game to overtime.
The Barons controlled the early part of the overtime but Philippe Cornet was sent to the box for slashing nearly two minutes in and Drew Schiestel put one past Barons' goaltender Yann Danis after a failed clearing attempt to give the Amerks the win.
“They just kept grinding,” Grant said. “We had a couple chances to put it away but I think this is a game where both teams are fortunate to get out with a point."
The Barons trailed 1-0 and 2-1 before the momentum shifted their way late in the second.
First, Grant tipped in a shot from Chris VandeVelde to tie it with less than two minutes remaining in the period.
Less than a minute later, Dan Ringwald knocked the puck to Ryan O'Marra off a clearing attempt and O'Marra blasted it past Drew MacIntyre to give the Barons their first lead.
