Behind first-half goals from Andy Dorman and Taylor Twellman, the New England Revolution completed the semifinal field with a 2-1 over the Harrisburg City Islanders of the USL Second Division on Wednesday night at Gillette Stadium.
The Revs moved on to the semifinals, where they will face the Carolina RailHawks of the United Soccer Leagues First Division on Tuesday, Sept. 4, at Veterans Stadium in New Britain, Conn.
The City Islanders' Matt Tanzini curled a 34-yard free kick into the upper right corner of the goal to cut the Revs lead to one goal in the 74th minute. Harrisburg's Anthony Calvano was shown his second yellow card of the game and ejected in the 89th minute.
Harrisburg had beaten MLS's D.C. United in the third round, so New England made no mistake, starting its first team against the City Islanders. The Revs advanced to the semifinals of the U.S. Open Cup for the first time since 2001, their only other appearance in the final four of the event.
Wednesday's Open Cup game was the first-ever Open Cup match at Gillette Stadium and the first in Foxboro since 2001. The game drew only 1,512 fans.
The Seattle Sounders face FC Dallas in the other semifinal.
