Fangraph's report: TLDR Big college corner OF with huge power, strong statistical performance and arm strength. Full Report Wallner hit for power all three years of college, even while pitching part time as a freshman and sophomore. He has some of the most explosive raw thump in the entire class, and will hit balls 10 rows into the bleachers even when he doesn't get fully extended. He has some moderate swing-and-miss issues characteristic of hitters who have power-driven approaches, but he's also willing to take a walk. His is a traditional right field profile, and he's in the mix with late first, early second round college power bats. https://www.fangraphs.com/prospects/the-board/2019-mlb-draft?sort=-1,1&type=0&team=
