Nike Big League Baseball Camp The Lawrenceville School Lawrenceville, New Jersey

Home » Baseball » New Jersey » Lawrenceville

Big League Baseball Camps has the same objective it has had for the past 65 years, to help every camper improve their skills.

The camp was originated by Lou Haneles. Mr. Haneles love of sports instilled in him a desire to operate a camp where athletes could not only come and learn the fundamentals of each sport, but a place where they could also enjoy themselves as well. Since 1980 the camp has been run by the Carlesi family. The Carlesi's consider all their campers and staff an extended family and conducts the camp with traditional family values.

Highlights Include

  • Lectures - Lectures are given on the fundamentals of the game.
  • Position Play - During the week all positions will be covered by our staff.
  • Drills - Drills are used to teach campers the skills necessary to succeed and the notion of teamwork.
  • Instructional Games - We want every moment of the week to be a learning experience for every camper. It is for this reason that during games, if a camper makes a mistake or does not execute properly, one of our coaches will show him what he did wrong and how to do it right.
  • Individual Instructions - Our camp is known for offering that personal touch and giving the individual attention some campers may need to truly learn and understand the game more thoroughly.
  • Teach To Understand - We want every camper to understand the reasoning behind the methods we use. It is for this reason that our coaches take the time to explain the reasoning behind why you execute a certain way.

At the Lawrenceville School, the outdoor facilities include two lighted artificial FieldTurf surfaces for Field hockey, Soccer, and Lacrosse, four baseball and softball fields, 12 combination Football, Field Hockey, Soccer, Lacrosse fields, one football game field, a nine-hole golf course, 12 tennis courts, a 400 meter all weather track, a state of the art ropes course, and a fitness trail.

Camp Director

John Carlesi

Director John Carlesi has been leading instruction for past 13 years. The current head baseball coach at Stuyvesant High School, John is a former Division II player and coach at St. Leo College (Fla.). John also served as Director of Staten Island YMCA baseball program.


We compile a highly qualified and professional staff each summer to teach at our camps. All of our coaches are adults who coach in their particular sport. These coaches are high school and college coaches, as well as, professional players and coaches.

We are lucky to have many of the same staff return each year which is important because we know the campers are receiving the very best instructions possible. Our counselors are often former campers who have gone on to college.

Since 1946 tens of thousands of campers have passed through our doors. Over the years we have had the satisfaction of seeing our former campers make their town league, high school and college teams, with some even advancing into professional sports.

Experience and trust are two factors that cannot be overlooked when exploring a camp for your child. Our experience in running sports camps is second to none. Over the years, thousands of parents have trusted us to not only teach their chidren, but also with their well being.

No camp, or business for that matter, would be around for this amount of time unless we were doing something right. We look foward to having the honor and privilege of showing you and your child what a great experience professional sports camps can be.

We have three boys and will definitely be returning

"My child was one of the younger kids and we were SO impressed with the way the instructors encouraged them and also encouraged the older kids to show good sportsmanship toward the younger ones. The camp was WONDERFUL. We are locals but I can't imagine sending my son to any other big campus camp that would measure up to this one! We have three young boys and will definitely be returning customers!!!"
