Pitching Instruction

Ari Ronick, Diamond Baseball of Boulder pitching coach, is offering local winter pitching lessons for Legion and Bison players.  Lessons are at Shining Mountain Waldorf School at 999 Violet Ave.

This is a great way for you to get ready for the upcoming baseball season. Lessons are  Sunday nights so as not to conflict with BHS winter sports and baseball workouts.
