Grace O’Sullivan Grace O’Sullivan 6'0" | SF Rivers | 2025 State New E (2025) | 6’0 Wing | Rivers

O’Sullivan has been a key element for Rivers and featured heavily in their important wins. The Princeton commit has measured attacks that are skillfully crafted. She’s one of the steadiest scorers on the team and gets clean looks off regardless of the defense’s response. Grace’s silky smooth shooting ability mixed with unshakable takes off the dribble make her a tough wing to stop. Her experience will come into play in Saturday’s matchup and considering the significance of this game, a player as capable as O’Sullivan is needed to get over the hump.

Grace is a top 10 player at her position. She is dynamic talent that capitalizes off team’s weaknesses. A complete player that will surely make an impact on the next level. Her mature game and her high IQ will serve her well at Princeton. The senior Rivers forward doesn’t have too many holes in her game. Princeton is a great fit for Grace.

Grace O’Sullivan was an impressive guard/wing prospect for MCW Starz 2025-P24 at The Clash. She used her length and strength to secure rebounds on both ends, force turnovers pressuring the ball, and demonstrated her multi-level scoring knocking down 3’s outside with strong finishes at the rim. One of her most impressive plays was when she scored through a foul with her left hand at the rim.

Grace had a big season as just a Freshman and looks to carry that momentum into her sophomore year. I think Grace has the game to be a potential division 1 college level player. She was an ISL HM All star last year and had games with 18 points and 7 rebounds. She is a 6’0 who has the skill set to be a force down low, or constantly stretch the floor and knock down threes. At the open gym I saw her play tough inside, and also shoot from the outside. She has a high motor, with good length to match her skill set. She can create her own shot and has proven she can play with high level competition. She is only a sophomore and should keep raising her stock.
