Knoxville Open: Pitcher Reports


PBR Tennessee Staff

KNOXVILLE, TN - The Knoxville Open was held on Tuesday, June 20th at Knoxville Catholic High School. This event was an open event that consisted of players from the 2024-2027 classes from Volunteer state, with many making their first appearance at a showcase style setting. Players went through an extended pro-style workout that included batting practice using Trackman, ran the 60-yard dash using Swift Performance, and much more. Pitchers were able to get numbers and metrics on TrackMan. There were some players who showed up and continued to build off of prior performances, but there were also some new names who jumped onto our radar with a strong showing at the event.

Continuing our post-event coverage for this event, we will be releasing our scouting reports from the event. First, we take a look our the scouting reports on all pitchers from the event.
