Greetings from the Wasatch Front and Rio Tinto Stadium.

Championship evening in Sandy, Utah as D.C. United visits Real Salt Lake in the 100th U.S. Open Cup final.

TV: GolTV, 9 p.m. ET. (Good luck finding it.)

Injury update: Luis Gil, Real Salt Lake exciting, young midfielder, underwent an emergency appendectomy Sunday night and is not available.

Cup tied: RSL defender Brandon McDonald, who played 27 minutes in United’s round-of-16 match against Philadelphia in June. As part of the trade, in which RSL relinquished a 2014 third-round draft pick and 2015 conditional selection, about 80 percent of McDonald’s $235,000 salary remained on United’s books for the remainder of the season. (He is out of contract at the end of the year.)

At stake: a berth in the 2014-15 CONCACAF Champions League and a $250,000 prize, which, per MLS’s collective bargaining agreement, is split among the players. Second place collects $60,000.

Road-trip eats: Park Cafe, where much of the RSL roster gathered for morning protein, and Ruth’s Diner in Emigration Canyon.

DCU: Hamid; Riley, Jakovic, White, Korb; Kitchen, Neal, Pontius, Thorrington, DeLeon; De Rosario. Subs: Willis, Iapichino, Silva, Porter, Woolard, Jeffrey, Doyle.

Silva is not injured, a club official says. Tactical decision by Olsen.

RSL: Rimando; Beltran, Salcedo, Borchers, Wingert; Beckerman, Grabavoy, Velasquez, Morales; Saborio, Plata. Subs: Attinella, Schuler, Alvarez, Grossman, Stephenson, Garcia, Sandoval.
