Start Here: Initial Evaluation and Skill Assessment — $40

Start here. Before training, we evaluate the player.

In person at 3525 Latrobe Dr., Charlotte, NC. What happens: in-person evaluation of the player — pitching and/or hitting, as applicable; assessment of strengths, limitations, and what to work on first; and a clear next step — whether that is individual sessions, and what to train first. What you leave with: an assessment of where the player is now, the 1–2 priorities to work on first, and a training recommendation — no obligation to book further sessions. Book the Initial Evaluation at tidycal.com/jimrooney46.

“I've known Jim Rooney for better than a decade, as a coach, a scout, and as a man. This guy is always ahead of trends and bases his work on what is best for the pitcher. Whether you need to learn the "in the trenches" stuff from a longtime baseball man or to break down the newest data, Rooney can be old school and new school, making Triple Spin a great place to learn for any pitcher.”

Tim McIlvaine - Scouting Director Los Angeles Angels

“From our days together working for the Milwaukee Brewers, Jim Rooney is one of the most impressive pitching minds I've come across. His ability to see a pitcher and almost immediately see where the disconnect in the delivery is stemming from is remarkable. Furthermore, he has the knowledge from the Ivy League classroom and from being a player, coach, pitching coordinator and scout to know what needs to be done to begin the process of adjusting the delivery to allow the body to get the most out of the individual delivery. Jim can help pitchers of all ages and is a wealth of information. He's a teacher at heart which helps him deliver a relatable, useful and impactful message. I wish I was around more people like Jim when I played because I would have been a better player. I'm excited to see that his thoughts will be out there for everyone now because I've certainly learned a lot from Jim along the way - and I know that everyone who signs up will too.”
