The 2017 Philadelphia Union season was the club's eighth season in Major League Soccer, the top flight of American soccer. The team was managed by Jim Curtin, his fourth season with the club. The Union finished the 2017 season with the same points total as the 2016 season, but did not clinch entry to the MLS Cup Playoffs. The 2017 season also marks a new goalscoring record by C. J. Sapong who scored 16 goals in a single season, eclipsing Sebastian Le Toux's record of 14 goals during the inaugural season.
During the 2016 MLS season the Union finished with an 11âÂÂ14âÂÂ9 record, which was enough for a playoff berth, the franchise's first since 2011, as the sixth seed. The Union also had a franchise record eight wins at home, finishing 8âÂÂ5âÂÂ4 at home and 3âÂÂ9âÂÂ5 on the road.
The Union faced Toronto FC in the Eastern Conference knockout round, where they lost 3âÂÂ1 at BMO Field. The Union's only playoff goal of 2016 was scored by Alejandro Bedoya in the 73rd minute of that game.
The Union entered the fourth round of the U.S. Open Cup playing host to the Harrisburg City Islanders and won by a score of 3âÂÂ2, advancing to play the New York Red Bulls in the round of 16, where a two-goal effort by Chris Pontius lifted the Union to a 2âÂÂ1 victory. The Union went on to lose 4âÂÂ2 in penalties to the New England Revolution after playing to a 1-1 draw through extra time in the quarterfinals.
