Skills Evaluation & College Recruiting Tools

Reminder - DBoB will be hosting our first ever Skills Evaluation and College Recruiting Tools Day!

NOTE: This event is ONLY open to Summer 2016 DBOB Legion players.

Please bring the skills evaluation form to your assessment.

When: Friday, May 27th.

  • B2 - 8:30 to 11:30 Set up and evaluation
  • B1 - 11:30 to 2:00 PM
  • A - 2:00 PM to 4:30 PM
  • C - 4:30 PM to 7:30 PM
  • (Please click here if you have a conflict. If we have enough interest, we'll consider a makeup date.)

What: Local baseball instructors Ari Ronick and Brett Manning will be conducting an evaluation day that will include filming and taking measurements for the following skills: Arm strength velocity from a crow hop, pitching velocity and deception in a bullpen session, running speed/agility, hitting exit velocity, on-field batting practice, infield and outfield skills and catching (throwing and blocking - optional). Ari and Brett will be using a radar gun and Zepp bat sensor to track the arm strength velocity and hitting exit velocity. Players will receive an evaluation report and the raw video footage to use for marketing themselves to college coaches. Players can also use the video with coaches to monitor progress throughout the summer.

Why: Individual player film and measurements can be used for the following:

  • as a baseline for improvement tracking for the younger players
  • to gain experience in a local showcase environment and format 
  • to market yourself to colleges if you'd like to play at the next level

Cost:  This skills evaluation session will be free for all 2016 Boulder Legion Players. This is a great deal for this experience, measurements and video footage compared to other showcases and/or recruiting services (which can range from ~$250-$3,600).
