Dallas got their two goals from second half substitutes Mauro Diaz and Maxi Urruti.
Twelve minutes into the match, the Union got their first crack on goal from Borek Dockal. The Czech native received the ball at the top of the 18-yard box and curled in a shot that just sailed over Jimmy Maurer’s goal.
Dallas had their first big chance in the 20th minute on a counter attack from Mosquera. The Colombian got the ball in the middle of the field as a Union defender stumbled to defend. He pushed the ball forward into the penalty box but his attempt on goal went just wide of the far post.
Twenty minutes later Dallas again came knocking on the Union’s door as Lamah chipped in a cross over the top of the Philadelphia defense to the run of Mosquera. Again the Dallas winger got in behind the Union defense but his shot on goal was pushed over the bar by Andre Blake.
The Union began to pick up some steam on the second half and nearly found the back of the net in the 58th minute. The ball got sent into CJ Sapong nine yards out from goal. The Union striker took a one-time volley that force Maurer into a big save.
Dallas finally made the breakthrough in the 63rd minute on a penalty kick goal from Diaz. The penalty was whistled on Auston Trusty for brining Matt Hedges down in the box on a corner kick. Diaz, who had just come into the match, stepped up and beat Blake with a low shot to the right side of the goal.
The lead then doubled in the 74th minute as Urruti was able to beat Blake at the far post. Lamah put in a perfect ball behind the Union defense where Urruti was able to force Blake to come off his line and he dribbled towards the end line before putting a shot to the far post.
