After grabbing just a single point out of a possible 18 in July and early August, Dominic Kinnear's men have put themselves back into contention with victories away from home against Kansas (3rd in Western Conference) and DC (1st in Eastern Conference).
The Quakes left the capital with a third consecutive clean sheet, and a third consecutive win to maintain their recent run of good form heading into the back end of the season.
Quakes defender Clarence Goodson was optimistic about his team's chances in the run in.
"When we looked at the schedule, the thought amongst the team was, we need to be in touch," Goodson said.
"We're very much in touch of a playoff spot. To be where we are is excellent. You look up the table, I think a lot of those teams have a lot of away games."
Goals from Chris Wondolowski and Shea Salinas either side of the break gave San Jose maximum points at the RFK Stadium.
The Quakes still sit two places adrift of a play-off position in 7th, but finish the season with seven home games out of nine.
