A 5-1 win over New York City FC on Wednesday has the Union in the final Eastern Conference playoff position, above DC United on goal difference, with the latter playing to a 0-0 draw with NYCFC last weekend.
Match preview
On Wednesday, the Union put their playoff desperation to good use, scoring three times in just over a half hour and pouring on the pressure throughout the 90 minutes.
That was their second triumph in their previous three league fixtures, and it has them back in control of their playoff destiny heading down the season's final stretch.
Jim Curtin's men have an opportunity this weekend to win consecutive MLS encounters for only the third time all year and the first time since July.
Philly have points in three of their previous four home matches in this competition but were beaten in their last league contest at Subaru Park against the Columbus Crew (1-0).
In 2024, the Union have been uncharacteristically poor at home, winning just three domestic affairs, tied with the San Jose Earthquakes for the fewest in MLS.
The Union are unbeaten in six successive competitive fixtures versus DC, winning the last two league matches against them in Chester by a combined margin of 7-0.
While most MLS sides were jockeying for a better position in the table this week, the Black and Red were idle with a few extra days to prepare for the stretch run as they aim to end a four-year playoff drought.
DC have claimed seven out of nine possible points from their last three league contests while losing just one of their previous six domestic affairs.
With a victory on Sunday, Troy Lesesne's men will not only move into a playoff position but also surpass their number of MLS wins away from home from a season ago (four).
The Black and Red are on a three-match winning run away from home in MLS and have won five successive road games across all competitions.
Their poor defensive structure has been their undoing in 2024, conceding the second-most goals in the Eastern Conference (57) with a goal differential of -13, while the Union are at +6, which at the moment is the only thing keeping DC out of a playoff position.
It has been over a decade since DC United last claimed a victory against the Union at Subaru Park, winning by a 1-0 score in May 2014.
