A stoppage time goal by Jacob Peterson gave the Colorado Rapids a 2-1 home win over Real Salt Lake on Wednesday to qualify the Rapids for the round of 16 of the Lamar Hunt U.S. Open Cup. Peterson also scored the Rapids' first goal of the play-in, which completed the octet of Open Cup MLS teams. Last year, Colorado eliminated Salt Lake in the fourth round of the U.S. Open Cup on a Peterson.

The third round of U.S. Open Cup play begins July 10.

Peterson scored his first goal three minutes into the second half after exploiting a weak punched clearance by Salt Lake keeper Chris Seitz, who was harried by Conor Casey's challenge. Chris Klein equalized for Salt Lake.

The MLS teams entering the third round are: Chicago, Chivas USA, D.C. United, FC Dallas, Houston, Los Angeles, New England, Colorado.
