The cup is awarded by the Committee of 10, a group of fans from each club, and the winner goes to whichever team owns the most points in games played between the rivals. Aggregate goals and current holders are the two tiebreakers.
Real Salt Lake took the most recent meeting, a 2-0 victory at the MLS is Back Tournament last month. Now the clubs reunite again on Saturday night at Colorado's Dick's Sporting Goods Park (9 pm ET | MLS LIVE on ESPN+ in the US and on DAZN in Canada.)
Roots of the Rivalry
The Rapids were one of 10 MLS originals in 1996, and they are one of five to keep their inaugural name. Originally playing at Mile High Stadium, home of the NFL’s Denver Broncos, Colorado’s early years were highlighted by a trip to both the 1997 MLS Cup and 1999 U.S. Open Cup finals.
But the club was somewhat geographically isolated, with the Kansas City Wiz (before their Sporting Kansas City rebrand) proving the nearest opponent. That all changed in 2005 when RSL joined MLS as an expansion team.
Proximity tends to brew disdain, and the club’s capital cities were linked by the sprawling Rocky Mountains. The "Rocky Mountain Cup" name was a natural fit, and they’ve since played 45 matches and counting.
One would think rivals wouldn’t trade or exchange players too often, but the Rapids and RSL didn’t abide by that logic early on. Look no further than a 2007 trade that sent Kyle Beckerman to RSL and Medhi Ballouchy to the Rapids. Defenders Nat Borchers and Chris Wingert also departed Colorado for their Rocky Mountain Cup rivals around the same time.
Beckerman, now 38, is RSL’s captain and playing his 14th season with the club. The defensive midfielder helped steer in RSL’s stellar 2008-'14 run, and Borchers and Wingert were fellow linchpins as the Utah-based club enjoyed great Concacaf Champions League and MLS success.
One of the most consequential matches between the two clubs took place on Oct. 25, 2008, the final day of that year’s regular season. A win for either club would guarantee a playoff spot and the Rocky Mountain Cup, but RSL just needed a draw to earn a postseason berth.
Colorado thought they were postseason dancing when Conor Casey scored an early goal, only for RSL's Yura Movsisyan to equalize in dramatic fashion for a 1-1 draw that . In one fateful moment, RSL retained the Rocky Mountain Cup as the previous winner, they made the MLS Cup Playoffs for the first time and also denied Colorado a postseason berth.
Another vital moment came in 2013, when Colorado took back the Rocky Mountain Cup after failing to do so in six straight seasons. The Aug. 3 meeting was their third of the season, and a 2-2 draw brought the silverware back to Dick's Sporting Goods Park. Colorado had claimed the trophy during the first two years, but it's been all RSL until today.
As the Rocky Mountain Cup has heavily tilted to RSL in recent years, they’ve enjoyed several blowouts against their rivals. None was more lopsided than a 6-0 victory over Colorado on Aug, 25, 2018 at Dick’s Sporting Goods Park.
RSL relied on five different goal scorers, with winger Jefferson Savarino netting twice and assisting once. Corey Baird also had a goal and two assists in coming off the bench. They led 2-0 at halftime and then drove the blade deeper with four second-half goals. Oof.
U.S. Open Cup
RSL holds a 21W-13L-11D all-time record in MLS play, an 11-4 Rocky Mountain Cup edge and they haven't lost since an Oct. 15, 2017 match. But these rivals have never met in the U.S. Open Cup.
Success for both clubs remains elusive in the historic tournament, though they’ve each finished as runner-up on one occasion. Colorado reached that stage in 1999, and RSL advanced to the final in 2013.
