Program Information


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

Expert Leadership and Counsellors

Under the leadership of Lee Mosbaugh, we have an exceptional staff of elite and university baseball players, professional coaches, and experienced instructors to teach and mentor your children. They bring years of experience paired with creativity and enthusiasm to make a positive impact on your child in a supportive and safe environment.

Players will be in groups of 6 with 2 Instructors.

Coach Lee is a staple in the Leaside Baseball Association. As director of baseball programming, he is responsible for our camp and development clinics as well as head coach for the 16U Elite team. Lee graduated from Humber College’s Sport Management program and played three seasons with Humber’s Varsity Baseball Program. His specialized development instruction and training is matched by his creativity and passion for working with young players. He’s a player and parent favourite in our organization.

Coach Parker started as a Leaside Baseball camper at the age of  5 and has now been a valued Camps and Clinics Instructor for 6 years! He is also part of the 9U AAA coaching staff, as well as getting top grades at University. Parker loves sharding his passion and enthusiasm for baseball with every player and is happy to go the extra mile for his players and peers.

Coach Henry has been playing AAA level baseball for over 10 years. Six years ago, he began instructing with the Leaside Baseball Camp and Development Clinics and is now one of our favourite Instructors. He enjoys sharing his knowledge and passion for the game with the young players while focusing on keeping the fun in all baseball activities. Henry has also been umpiring with the LBA for over five years - acquiring his Level 3 umpire accreditation and becoming the Umpire in Chief for the LBA - conducting clinics and mentoring young umpires.


The LBA also provides all required baseball equipment including balls, bases, bats, and helmets. Equipment will be sanitized periodically during the session

Players should wear comfortable athletic clothing, a mask that comfortably covers their mouth and nose, appropriate running shoes or indoor cleats, and an athletic cup is required for age 8 and older. They should bring their baseball glove and water bottle. IF they have a bat and helmet, they are welcome to bring those too.
