Organization Prospect Rankings

• 
  Ranked Washington Nationals #10 prospect in 2026
  BA Grade/Risk: 55/Extreme
  
  Adjusted Grade: 35
  
  Track Record: Harmon threw the best fastball of any high school righthander in the 2025 draft class and trailed only lefthander Jack Bauer among all prep pitchers. Harmon helped pitch East Union High to a Mississippi 2A state title in 2025, the program’s second in three years. He was committed to Mississippi State before he aligned with the Nationals in the third round and signed for $2.5 million, a bonus akin to a top-40 overall pick.
  
  Scouting Report: Harmon is a projectable 6-foot-5 righthander with long limbs and a high-waisted frame. He is tall, lean and flexible with a loose arm that generates easy velocity. Harmon sits in the mid 90s and has been up to 98 mph with riding life and late cutting action to his glove side. His delivery is clean and repeatable, and he throws strikes from a three-quarters arm slot and slight crossfire landing. Harmon’s fastball has double-plus potential and could top out at 100 mph one day, but his secondary pitches need more work. He throws a low-80s sweeper and a slider in the high 80s, both of which he can locate well for his age. Refining them into above-average pitches will be a key development goal. He occasionally throws a low-80s changeup that will be another point of emphasis. Adding strength to his frame and testing his stuff against professional hitters to see what needs to be tweaked are the next steps.
  
  The Future: High school righthanders are among the most volatile draft commodities. Harmon has a great foundation for the Nationals to build upon, as they did with Travis Sykora from the 2023 draft, but it will be years before the righthander’s full potential comes into focus. The Nationals will likely hold Harmon back in extended spring training, as they did Sykora, before assigning him to the Florida Complex League or Low-A Fredericksburg in 2026.
