Defenceman Stuart Percy also scored a late goal for the Leafs.
Since every Leafs player is new to Babcock, even core players were under the microscope. Goaltender Jonathan Bernier stopped 28 of the 29 shots he faced in making a strong start to what Babcock characterized as an open competition with James Reimer.
Andrew ``the Hamburglar'' Hammond, who led the Senators' improbable run to the playoffs last season, stopped 16 of the 18 shots he faced before being replaced by Chris Driedger. Mike Hoffman scored for Ottawa.
