Scoring goals has not been a problem lately for the Chicago Fire. Preventing them, however, has been the story of consecutive losses that have kept the Fire from climbing the Eastern Conference table. Chicago will try to deliver a better defensive performance at home Wednesday night against the Philadelphia Union. The Fire (4-10-6, 18 points), who are in the Eastern Conference cellar, have taken 4-2 and 2-1 road losses in their last two matches against Orlando and Seattle, respectively.
