SANDY -- Two failed markings.
At the end of the day, that's all it took to spoil an otherwise solid performance by Real Salt Lake.
San Jose's Steven Lenhart scored twice on unmarked headers during a wild three-minute span of the opening half of play, and that was the difference in a 2-1 decision at Rio Tinto Stadium on Saturday night.
"It comes down to focus and commitment," Real boss Jason Kreis said. "We had all the momentum. And we don't do a good enough job and now guys are hanging their heads."
Both goals came during a wild four minute sequence that saw all three of the matches goals come in short succession.
It all started with Lenhart's goal in the 18th minute off a cross in from Cordell Cato that found the striker nearly unmarked in the middle of the box for 1-0 advantage.
The goal, which came completely against the current run of play, was just the third that Lenhart had scored this season.
Salt Lake answered back quickly.
Less than a minute later, central midfielder Javier Morales leveled the scoreline at 1-1.
With midfielder Kyle Beckerman swinging a corner kick inside the 6-yard box, Morales broke free from his defender and toe-punched the ball off the crossbar and behind San Jose goalkeeper Jon Busch, who was directly in front of the shot.
Morales' goal briefly brought a sense of relief to the home side after conceding the shockingly easy goal, but neither the Earthquakes nor Lenhart were done yet.
Just two minutes later, the San Jose forward latched onto a free kick from Shea Salinas on the right side of the box and headed it home to put the Earthquakes back in front.
After regaining the lead, the visitors quickly slid into slowdown and bunker tactics, keeping the majority of their team behind midfield to and ceding possession to Real.
RSL finished with a 69.5 to 30.5 percent possession advantage for the match, and made 526 total passes to just 213 for San Jose.
Real boss Jason Kreis even switch to a 3-4-3 in the waning minutes, subbing in an extra forward and sending central defender Nat Borchers forward often to create additional pressure and size mismatches.
Despite the commanding edge in every appreciable statistic, including a 17-8 advantage in shots, Salt Lake couldn't break through for the equalizer in dropping its second straight match.
