After entering his senior year as a virtual unknown, Marquetti helped take a Millikan squad that finished with a 14-15 record last season to a 21-9 finish this year, earning a scholarship to USC in the process.
Looking back on his senior year, Marquetti is pleased with what he accomplished.
"I improved on pretty much everything," Marquetti said. "I'm really happy with how I started the season and I finished pretty steady I think. I'm happy with how my team played this year.
"I feel I was able to take on other ranked players individually, while I also did what I needed to do for my team with my scoring, making free throws and I led my team in almost every category."
After watching Marquetti early into his senior year, it didn't take USC long before offering the versatile forward. About a month after that offer, Marquetti ended his recruitment before long, pledging to Andy Enfield's program.
Since that commitment, Marquetti has stayed in close contact with the USC coaching staff.
"I've been talking to them and going to games," Marquetti said. "I'm feeling pretty good about my decision."
USC has talked to Marquetti about playing early into his career and that's one of his goals as a freshman.
"I believe if I keep working I can come in there and play big minutes as a freshman and sophomore," he said. "The coaches are hoping I can help them when I get there.
"I think I can come in and play the style of play they want. I think I can contribute with my scoring and rebounding right away."
Marquetti isn't going to outline a long list of goals for his USC career but is clear about one expectation for the next level.
"I expect to keep improving," he said. "Both as a team and as a player."
