Barco, Atlanta United rally for 1-1 tie win Union
Defending champion Atlanta (0-1-2) used a series of quick passes to move to ball from the left to the right side where Julian Gressel first-timed a high entry and Barco side-netted a header inside the far post.
Brenden Aaronson, an 18-year-old homegrown making his MLS debut, ripped a right-footer that, as it went through the legs of Leandro Gonzalez Pirez, deflected off the defender’s leg past goalkeeper Brad Guzan to give Philadelphia (0-3-0) the lead in the 47th minute.
Atlanta had 71.4-percent possession — finishing with 669 passes compared to just 267 by the Union — but came up empty on a handful of chances. Josef Martinez, who set an MLS record with 31 goals last season, missed wide left on a shot early in the second half and later had his bicycle shot stopped by goalkeeper Andre Blake.
