The Belgium international came off the bench in Santa Clara for his first outing of pre-season, taking just 14 minutes to make a telling impact when opening the scoring.
Origi was a constant threat at Levi's Stadium in the eventual 2-0 victory, as he looks to push on from a solid campaign last time out that saw him score five times in the Reds' final six games of the campaign.
"It can be [a big season for me]. I still have to work a lot and there's a lot of room for improvement, but I try to learn day to day and we're learning as a team also," he told the Liverpool Echo.
"I can feel the confidence from everyone and can improve and enjoy my game. Year by year I'm improving and I'm still young. The most important thing is to make steps and last year I had some good moments, so I want to learn and become more consistent to help the team even more and become an important player in the team."
