5-11/170...bat-first 2026 RHH OF/1B/RHP with plenty of upside...body looks great, added muscle, physicality will likely be a value...on the barrel in BP, loud BP with deep drives to pull-side, 87.7 Trackman Exit Velo with best distance to date at 15 yrs old, looking like power will be a big part of his game, on track to develop into a middle-of-the-order power bat & run producer...defense doesn't come as easy as barrels, moves good in OF with LF profile, more comfortable at 1B where he's probably best suited...2026 with arrow going up for sure, one we will keep an eye on and colleges will as well.
