With Spezza's two-goal game on Monday afternoon, he surpassed Alexei Yashin (218G) on the all-time Senators scoring lead.
Spezza is also second, behind Alfredsson, in career assists and points with the franchise, although he'd surpassed Yashin in those measures long ago.
After Spezza, the next-highest-scoring current Senator is Chris Neil, whose 86 career goals in a Senators uniform put him at 11th all-time. Milan Michalek is quickly closing in on him, though, with 65G (which puts him at 15th all-time).
It's somewhat ironic that the main player acquired in the deal that sent Yashin to the New York Islanders has now bumped the much-maligned centreman out of the team's top two goal scorers of all time, but it will take a long time before another Senator bumps Yashin further down the goal-scoring list.
