Official Scouting Report

  • Class Rating
  • LHPPosition Projection

10/01/2023 - National Showcase - Trenton, NJ Nathen is an athletic LHP who will graduate in 2024. On the mound, delivery is sound and repeatable allowing his quick arm action to work well to the plate. Fastball shows a range of 72-76 mph with arm side run on a downhill plane. Breaking ball displays 2/8 shape with gradual break. He maintains arm speed on his changeup with arm side run. Control is solid as he throws strikes with all his pitches. Stock on the mound will continue to rise as he builds more arm strength through a long toss program and throws more strikes. Nathan has potential with time and room to progress his game.

Tool Grade Scale

Our main goals with the BF "10-70" Scouting Scale are to provide the player with a realistic evaluation of his "PRESENT" abilities (what he can do today), and to provide college coaches with information they can use to identify and/or compare potential recruits.

Tools are graded for all players and pitchers, regardless of age or graduation year. However, for High School players we use only grades 20-70 (grades 10-18 do not apply), while for Middle School players we use only grades 10-52 (grades 55-70 do not apply).
