The Ottawa Senators signed left winger Clarke MacArthur to a five-year, $23.25 million contract extension Tuesday, taking care of one major piece of off-season business.

MacArthur, who has one year and $3.25 million remaining on his current contract, is now under contract through the 2019-20 season. The extension calls for him to be paid $4.5 million in 2015-16 and 2016-17 and $4.75 million in the following three seasons.

MacArthur scored 24 goals and 31 assists in 79 games with the Senators last season, finishing fourth in team scoring.
