Two goals from Cory Burke pushed the Union past the Chicago Fire and into the U.S. Open Cup final for the third time in club history.
Burke, who got the start over Sapong on Saturday night, found the net in the 59th minute. Alejandro Bedoya found the forward with an exquisite chipped pass, and Burke took it down and slammed it past an outrushing Richard Sanchez.
The Jamaican forward doubled his tally in the 77th. Picking up a great pass from Bedoya yet again, Burke made a strong run down the center of the field and blasted his shot into the back of the net.
