From a Reuters story about the Edmonton Oilers' ninth playoff win in 2006:

Roloson finished with 31 saves for his eighth victory of the playoffs.

If a team has just won its ninth game of the playoffs, and the goaltender in question has played every goaltender minute of each of those nine wins, how is it possible that he just received his "eighth victory" of the playoffs? Aaargh!
