A member of the class of 2029, Grivna is rated as a four-star recruit by ESPN and Rivals, both of which slot him in the top 20 of his class. (247 Sports is yet to release any 2029 rankings.)
Grivna attends Ballard High School in Louisville, Kentucky. He is listed as a 6-foot-11, 220-pound center.
Mason Grivna scouting report

A dominant two-way player, Grivna is equally potent on both ends of the floor. Offensively, it all starts with his post-up game.
He seals hard and, after making a catch, uses his body to carve out space and then finish at the cup. He isn’t extremely flashy on the block, but Grivna gets to his spots. And, of note, he has relatively soft touch on floaters and bunnies.
In transition, Grivna is an excellent rim runner. He sprints hard and he is a surprisingly fluid mover for his age and size. His jumper is also thoroughly encouraging.
Listen to me.. This kid is going to be a name you hear a lot hear soon..

Although it’s fairly slow, it’s mechanically sound and, most importantly, he hits it. And for a 6-foot-11 sophomore in high school to be effective in any manner as a shooter is flat-out impressive – and, of course, signals he’ll be an inside-out threat in college.
Defensively, the most eye-catching aspect of Grivna’s game is his discipline. Players with his size and length tend to jump out of their shoes, leaving their feet on every ball fake and eyebrow raise. But Grivna just consistently walls up, gets a good contest and then erases a shot once it leaves an offensive player's hands.
He’s also, again, unexpectedly mobile and although he won’t be clamping up guards, Grivna can survive against more athletic forwards. And he’s naturally excellent in help side.
How would Mason Grivna fit at Indiana?

It’s far too early in Grivna’s high school career to make any concrete predictions. And one can only imagine the state of Indiana’s roster come 2029-2030.
But Grivna isn’t getting any smaller – which means his shot-blocking and rebounding will always be a strength. Presumably, he’ll continue to grow as a post player and if the jumper also blossoms, he’ll be an extremely versatile two-way threat by the time college rolls around.
