From her 2026 freshman-season profile
Three straight errors on a targeted float in August — then six clean, four perfect. An error on ball one against Summit — then five perfect passes on seven. Across her freshman season, she did not have two bad matches in a row: after a 0.75 on four at San Dimas, she passed 2.13 on 15 against Los Altos and 2.25 on 16 against Colony — 18 perfect passes in two matches.
24 aces in 45 sets at 89% in — a season-high seven against Los Altos, and four consecutive to open a tournament match. Opponents pass noticeably worse off her serve than off the team average.
Her rating is earned from right, middle and left back — three zones, three angles to the setter — because that is where the lineup card has asked her to be. When the setter is pulled, she has delivered 45 out-of-system sets without an error.
One set at libero at the Santiago Tournament — seven attempts, a 2.57 pass, seven digs, zero errors — then four full matches at libero to close the season. The first three each topped the last — 2.00 at Colony, 2.15 against South Hills, and 2.25 with ten perfect passes on a season-high 16 attempts in the Colony rematch. Fifty-eight serves received at libero, 31 of them perfect, at a 2.03. The per-ball numbers hold when the volume goes up.
