About the Union: The Union are coming off a Sunday matchup against the Red Bulls in which the Union rallied from a 2-0 deficit to record a 2-2 draw. Winger Chris Pontius led the charge, scoring a goal and drawing a penalty kick for another. He leads the team with seven goals this season and ranks second with four assists. . . . In 2014, the Union played the Revolution in the U.S. Open Cup quarterfinals. Philadelphia won that contest, 2-0, but the team also had home field advantage. The Union have won only one game on the road this season, a 2-1 win over Columbus on March 12. Wednesday's game will mark the first time the Union will not be the home team in a 2016 Open Cup game.

About the Revolution: The Revolution's leading scorer is not a forward but a midfielder. Lee Nguyen, who has started all 19 games, tops the team with five goals. He also has seven assists this season. ... Forward Kei Kamara has made a strong first impression since he was traded from Columbus in May. In his last four MLS games, he scored three goals, which is not surprising considering he finished 2015 with 22 scores. . . . The Revolution entered Tuesday with the worst goal differential (minus-7) in MLS. . . . New England, which is in sixth place in the Eastern Conference, won the Open Cup in 2007.
