Riley Stringer Riley Stringer 5'11" | S/RS Mater Dei | 2028 State #46 Nation CA has always been one to watch, and her performance last night showed why younger athletes should watch and emulate her.

In my piece on juniors running the most offense, Riley averaged 5.0 assists per set (462 assists over 92 sets). She is ranked No. 1 in the state among setters and right sides.

Riley ran the Mater Dei offense with control. She delivered to all of her hitters and kept the communication constant. She finished with 25 assists (8.3 per set), an ace and 4 digs. She reads the ball off the pass. She plays with discipline on defense, getting the ball up on the right side and staying back where she needs to be. She was also consistent at the service line, including delivering an ace. Before the match, Riley told me she controls the pace by staying calm and collected when the team feels anxious. That is the job a setter has in a playoff match, and she handled it.

“As a junior setter, I’m able to control the pace of a playoff match by staying calm and collected when the team is feeling anxious and getting hype when the energy is low!

This CIF run is so important to me because getting to play such good exciting volleyball with my best friends is such a blessing!”

Riley Stringer’s first varsity season at Mater Dei has put her in the middle of one of the best programs in the country. She has 484 assists through 98 sets, averaging 4.9 per set, along with 33 aces and 122 digs.

Setters earn trust through decisions, not highlights. Riley understands that the work starts with knowing who she’s setting.

“What I learned about running the offense at Mater Dei is truly how important it is to learn your hitters. What specific set is going to make them the most successful and what kinda relationship you need to set with them in order for trust to grow.”

That is a setter thinking like a coach. Her time at the NTDP this summer took it a step further.

“The NTDP summer training changed the way I strategize during the game. It’s not always about how well you set, but what opportunities you create for yourself and for your teammates. It made me reach a new level of play because now I’m able to keep the other team’s defense guessing.”

She operates with the awareness of a setter who sees the whole court, including the blockers on the other side. As a 5-foot-11 S/RS, she is a real attacking threat herself, so that unpredictability is built into her game.

“What made Hawai’i feel like the perfect fit was the coaches and culture. Coach Joshua, Heather, Will, and Kolby are really amazing human beings and I have so much respect for their commitment to the game. I love their competitive fire and kind spirit! What I love about the culture of Hawaii is that it’s all about family. You know that you are coming to be a part of something bigger. It’s such an honor to not only represent the school but to represent the state of Hawai’i!”

Hawai’i is getting a setter who builds trust with her hitters and keeps defenses guessing. Those are the habits that win at the next level.

462 assists | 92 sets | 5.0 per set

Riley Stringer Riley Stringer 5'11" | S/RS Mater Dei | 2028 State #46 Nation CA has been on the floor for 92 sets for one of the deepest programs in the country. On a loaded roster, per-set assist numbers often reflect how a team distributes the ball, so coaches should read her line alongside Mater Dei’s system rather than in isolation.

Her profile extends well beyond this list. The 5’11” setter is ranked No. 46 in PrepDig’s Class of 2028 National Rankings and earned an invitation to the 2026 USAV NTDP Summer Training Series. She was named MVP at the SoCal PrepDig Top250 Showcase and a Top Performer at PrepDig’s Exposure Tour. When asked what she is most proud of, she didn’t point to a stat. “The part of the game I am most proud of is the people I have met along the way.”

In Riley’s Words

Riley Stringer did an excellent job tracking the pass and understanding her options before contact. She stayed active with her feet, watched the ball from platform to target, and delivered based on the situation in front of her. She showed a strong understanding of her own strengths while running the offense.
