Despite a few lineup changes and some inspired play in the first 45 minutes, the Union couldn't change their recent bad fortune.
A costly turnover broke a scoreless tie in the 52nd minute, and the Union couldn't rebound in Friday's 2-0 MLS loss to New York City FC before 16,553 at Talen Energy Stadium.
The Union (0-4-2) have dropped four games in a row and are 0-9-4 dating back to September of last season.
New York City FC (3-2-1) capitalized on a turnover to open the scoring. Ronald Matarrita stole the ball from Union defender Keegan Rosenbery and made a great touch pass to Jack Harrison.
