Cartwright, a 6-foot-1 guard, scored 12 points on 6-for-12 shooting, plus tossed out five assists and recorded a couple of steals in Flintridge's win.
"It was hard for me to find my jump shot in the first half to be honest," Cartwright said. "But in the third quarter a couple started to go down and I tried to make a couple of nice passes. Defensively I think I worked hard."
"Usually I'm more of a three-point shooter, but today I took a lot of jump shots," he added. "They were really sagging off of me a little bit. I was looking for some jump shots. I like to attack and get my teammates involved."
Cartwright is an intense player that plays hard on both ends of the floor. To go with his ability to shoot, create for teammates and handle the ball, Cartwright is a very good on the ball defender.
"I'm just trying to be a floor general and a leader out there on the court," he added. "Trying to do what I can to help my team win whether that means scoring, dishing or just playing hard defense. I just try to do what I can to help my team win."
"Defense is a huge part of the game," he added. "If you don't have a great offensive game, you can always have a good defensive game."
On Wednesday, Gonzaga was at the game to evaluate Cartwright, but he's had a host of other programs check him out this year. Among the schools involved include LMU, Stanford, Harvard, Princeton, Rice, San Diego, Arizona State, Boston College and Cal Poly.
"It's going fine," he said of his recruitment. "It's hard to say. There are schools that fall in and out. There's some schools that I really, really like, but I'm just trying to play right now. I don't want to think about it too much."
Cartwright has unofficially visited two schools.
"I've seen San Diego and I've seen Rice," Cartwright said. "Those are the two schools I've seen. I'm not going to take any officials for a while. I'm going to see where my recruiting is in the spring and see who is still there and who is new."
