Baseball Training with Jim Ambrosius

Meet Jim Ambrosius!

Hey everybody, my name is Jim Ambrosius. I am passionate about sharing my knowledge with baseball players, softball players and coaches. What makes me qualified to teach the game of baseball and hitting in softball? Here are my credentials. As you’ll see, I’ve had good fortune to experience a lot with the great game of baseball:

Collingswood Panther and Brooklawn Legion – While playing for Collingswood, I was a 2-time member of the All-South Jersey 1st Team, and a one-time All-State member. I was named to Collingswood’s Athletic Hall of Fame in 2010. I played for Brooklawn American Legion, where I was widely recognized by many as the most accomplished American Legion baseball program in the United States.

ECU Pirate – I played at East Carolina University on a full scholarship. I had a solid career at ECU while battling with arm injuries.

Explorer to Phillie – After 3 years of recurring arm injuries, I decided I wanted to convert from a pitcher to a position player. That is when I transferred to LaSalle University to play outfield. I had a good year offensively, and I ended up signing as an undrafted free agent with the Philadelphia Phillies. I had a good little run with the Phillies, however, as my arm injury persisted, I knew my playing career was coming to an end. I then discovered I wanted to take my knowledge elsewhere.

Coaching – My first coaching experience was as a pitching coach at LaSalle University. However, I wanted to run my own program, so I decided to take on a high school coaching job. In my 12 years as a varsity baseball head coach at Kingsway Regional HS and Williamstown HS, we won 6 conference titles. In my 9 years at the helm of Williamstown’s baseball program, we won 5 conference titles. During the final 5 of those seasons, Williamstown was regularly ranked in the top 15 teams in South Jersey. In my 2 years as a pitching coach for Brooklawn American Legion, we won 2 state championships. In my 2 years as head coach of West Deptford American Legion 20 years apart, 43W-8L in 1999 and 23W-4L in 2019, our teams had a combined record of 66 wins and 12 losses, coming up just 2 wins short of making the American Legion World Series in 1999. Over the years, I’ve also worked with 1 big-leaguer, 7 pro players, 30+ Division I scholarship players, and over 100 college players. Working with these dedicated players has helped me to understand what it takes to be great at the sport.

Complete Game Baseball and Name Your Sport In 2014, I started my own private instruction business, Complete Game Baseball. I’ve worked with hundreds of players in a one-on-one, small group, and team setting over the past 7 years. Now, I have taken my business over to Name Your Sport, where I can train using HitTrax equipment.
