Although only a freshman, Grivna is a matchup nightmare for every team in the state. Ballard barely escaped Male on Tuesday night in a top-notch quarterfinal showdown but it was an assist from Grivna that sealed the deal. He’ll enter tomorrow’s game averaging 16.5 PPG and 9.3 RPG on 69/49/73 shooting splits. Surrounded by an ample supply of elite shooting options in 2026 WKU signee Cole Edelen Cole Edelen Cole Edelen 6'0" | PG Ballard | 2026 State KY , 2028 standout Baron Clay Baron Clay Baron Clay 6'3" | PG/CG Ballard | 2028 State KY , and fellow 2029 Qyntin Woods Qyntin Woods Qyntin Woods 6'1" | SF/SG Ballard | 2029 State KY , teams have struggled to defend the three while balancing the attention that Grivna demands.

Flat out, Grivna had maybe the best performance I’ve ever seen a freshman in Kentucky have in my almost 4 years of scouting the state’s top talent. Grivna had a handful of dunks, with a few coming off quick spin moves in the post that left the defense in the dust. Knocking down a pair of 3-pointers, Grivna can make you pay if you give him time and space beyond the arc. With excellent hands and patient moves with his back to the basket, Grivna plays the game with the polish and poise of a player much older than he is. While it’s very early for 2029 prospects, Grivna looks like a high major target and a player who will be nationally ranked when those rankings are released by various outlets.

Mason is a potential top 25 prospect in America in the 2029 class, in my opinion. An excellent shot blocker whose offensive game continues to improve, Grivna is likely not done growing. With his fluid athleticism and the way he is consistently improving, Mason could be the top player in this class for a long time.

Ballard’s next star, Grivna has the potential to be a top 25 or so prospect in the 2029 class, nationally. Already an elite shot blocker, Mason’s offensive game is good and getting better. Most importantly, the big man plays with a good motor and isn’t afraid to mess up. His prospect ceiling is way up there.

It’s obviously super early but Grivna looks like a top 30 talent in the nation in this class. Mason is a fluid athlete and not super clumsy like most bigs his age. A high floor/high ceiling player, the 6’10 Grivna is already a really good rim protector with strong defensive instincts. Likely still growing and will eventually pass the 7 foot mark, Mason has the potential to be the best Center to come out of Kentucky in a while. He’s got a long way to go but Grivna is more advanced than Malachi Moreno was at the same age.

One of the biggest posts in the state already, Grivna has a ton of potential and could be one of the best “bigs” that Kentucky has seen in a long time if he reaches his ceiling.

I was very impressed with Grivna’s two way impact as a rising freshman playing against one of the top teams from the Cincinnati area on Sunday. An impact shot-blocker at the rim, Grivna has an advanced feel for contesting without fouling and simply using his length to alter shots instead of needing to block everything in sight. Offensively, Grivna caught contested entry passes and displayed soft touch on mid-range looks. Very impressed with his skill level at a young age and expect Grivna to continue to improve over the years as he builds strength and confidence with the ball in his hands.

The literal biggest name in 2029 in Kentucky right now, Mason is a legit 6’9 post player who moves well for his size and should make an immediate impact at Ballard this winter. Don’t be surprised if Grivna is 7 foot tall in the near future.
