Craig Anderson has 36 career wins (so far) with the modern-day Ottawa Senators. Clint Benedict, who Anderson honoured on his heritage mask, had 98 career wins with the original Senators franchise.
Ahead of Anderson are Patrick Lalime (146 wins), Ron Tugnutt (72), Ray Emery (71), Damian Rhodes (65), Brian Elliott (59), and Martin Gerber (49). If Anderson can maintain his level of play throughout the duration of his current contract with the Senators, he could very well take over the all-time lead in wins with the franchise.
There are two goaltenders who've played more games with the Senators than Anderson, but have fewer wins: Both Don Beaupre (71GP, 14W) and Craig Billington (72GP, 11W) had some tough times in Ottawa. In 64 career games for the Senators (one fewer than Anderson has, as of this morning), original franchise goaltender Peter Sidorkiewicz had just eight wins.
Current Sens backup Alex Auld has 17 career wins during two stints with the team, good enough for 11th all-time for the franchise.
