Jurgen Klinsmann's men picked up a 2-0 win in a friendly fixture with Azerbaijan on Tuesday, and have now lost just once on home soil since a 4-1 defeat to tournament hosts Brazil almost exactly two years ago.
The Americans have won 17 of their 20 home matches since that loss, and Klinsmann will be keen to harness that winning mentality heading into the global showpiece.
Goals from Mikkel Diskerud and Aron Johannsson won that match, but it was an injury scare for Clint Dempsey prior to kick-off that caused the most talking points in San Francisco.
The Seattle Sounders forward was left on the bench throughout, but Klinsmann was quick to allay any fears he may not be ready for the finals and expects him to feature in Sunday's clash.
"He's all good," Klinsmann confirmed on Thursday. "Today they have an easy regen, travel day.
"So by tomorrow (he will be) full speed in training. Everything is good."
Fatih Terim's men were disappointing in qualifying as they finished fourth in Group D behind eventual winners Netherlands, as well as Romania and Hungary.
"We're looking to continue our fitness," he said after the win over Azerbaijan.
"(To) continue building our relationships on the field and obviously defensively we want to work on how organised we can be and how difficult we can make it on other teams."
