With Kostroun in the middle, Roots 17-1 Green will take the court in the 17 USA division. An extremely physical player, she has a strong presence at the net for them and can be very difficult to stop offensively when she gets into a rhythm. Kostroun is tall, athletic and very powerful, a combination that contributes to her offensive efficiency as very few blockers are capable of handling her hard swings. She also makes a big impact with her blocking, moving very well at the net and doing a very good job of sealing the space with her arms.
