Scout Report
When you're suiting up alongside some of the nation's most elite prospects at Sierra Canyon, standing out requires a special blend of talent and basketball IQ.
Background
The Chatsworth, California native has found himself in the perfect development environment at Sierra Canyon, where he's learning alongside future college stars like North Carolina commit Maximo Adams and Cal-bound Brandon McCoy. Playing in one of the most competitive high school programs in the country has accelerated his development and put him on the radar of major college programs. His journey through the prestigious Sierra Canyon system has provided invaluable experience against top-tier competition.
Playing Style
Martinsen brings prototypical small forward size at 6-6 with the versatility that modern college programs covet. His ability to play multiple positions and contribute in various ways makes him an attractive prospect for coaches looking for lineup flexibility. While playing alongside higher-ranked teammates, he's developed into a reliable complementary player who understands his role within a talented system. His basketball IQ and team-first mentality have been key factors in his recruitment, as he's shown the ability to impact winning without needing the ball in his hands constantly.
Recruitment
With nine Division I offers already in hand, including major programs like Arizona, Stanford, USC, and Arizona State, Martinsen has established himself as a legitimate mid-major to high-major prospect. His ranking at #160 nationally in the 2026 class reflects solid recognition, though his recruitment could continue trending upward with strong performances in his junior season. The geographic diversity of his offer list, spanning from Pac-12 powerhouses to Ivy League programs like Harvard, suggests versatility in both his game and academic profile.
