Philosophy
Great Person. Great Athlete. Great Player.
The core philosophy of Leaside Baseball is to help players learn the game and develop their skills in a safe, positive, inclusive, and fun environment.
We welcome boys and girls of all experience levels.
Through the teaching and refining the fundamentals of baseball – throwing, catching, hitting, running, jumping, sliding and much more – your child will gain a greater understanding of the game. Learning in a fun and supportive environment, players become more comfortable and skilled with the movements.
Instructional Highlights
- Demonstration and hands-on practice of correct hitting, fielding, base running, throwing and catching mechanics
- Baseball instruction, drills and situational game play scenarios
- Batting practice and hitting drills using machines, instructor toss and tees
- Baseball-specific athletic training to improve upon speed, agility, hand-eye coordination, balance, strength and flexibility
