Game #2 - Chicago Fire 3, Philadelphia Union 1 - August 12, 2012 at PPL Park
Nearly five months after their first meeting of the season, the Fire traveled to Philadelphia in August with hopes of snapping the Union's five-match home unbeaten streak.
This match should in part be remembered for the heroic efforts of Logan Pause who suffered a partially collapsed lung and broken ribs after a 25th minute collision with Bakary Soumare. The Fire captain continued playing with the injury for nearly 20 minutes before being substituted just before halftime.
As for the scoring, Philadelphia took the early lead, capitalizing on Freddy Adu's 35th minute cross which took an awkward bounce and saw defender Jalil Anibaba score an own goal.
Making his first start for the Men in Red, Sherjill MacDonald would lead the comeback in the 43rd minute when he breezed past Soumare on the right and centered for Chris Rolfe who coolly finished for the equalizer.
Fire defender Arne Friedrich would tally his first goal for the Men in Red, heading home Marco Pappa's corner kick in first half stoppage time to take the Fire into the break up 2-1.
Rolfe would ice the game just after halftime as Patrick Nyarko fed him towards the box on the right before unleashing a right-footed blast past Zac MacMath in the 56th.

Feeling the heat, the Fire responded almost immediately as Patrick Nyarko laid off for Dominic Oduro who slid his slow-rolling effort inside MacMath's right post.
The Fire's push for an equalizer took a serious blow late as Guillermo Franco went in for a clumsy challenge on Union defender Brian Carroll, forcing referee Abby Okulaja to show the former Mexican international red in the 79th minute.
