baseball Camps » Baseball Summer Defense Days

The Baseball Summer Defense Days program is designed to prepare players for upcoming tournaments and showcases. This specialized program gives players the opportunity to focus on position-specific training. Emphasis will be placed on improving the physical and mental aspects of the game. Sessions will be coached by Mannino’s professional instructors. They will be formatted like a college practice to ensure high quality, high repetition training.


In order to keep our player to coach ratio low, we have limited registration availability for each position. We have spots open for:

6 Catchers

10 Infielders
