OUR TEAM
The Team Behind
Union Baseball Systems
Top to bottom, Union Baseball Systems has by far the most dynamic baseball training and coaching staff in San Diego, and we’re only going to get better. UBS uses the same systems and processes to identify, interview, and hire progressive, high ceiling coaches that Bobby used with the Chicago Cub’s top-ranked farm system – providing training to ensure quality across all our staff.
Founders
In an effort to bring the most advanced, progressive baseball training to San Diego, UBS was founded by former college teammates…
Bobby Basham

Bobby has close to 20 years of experience in professional baseball – with 7 seasons as a player and 12 at the front office level. He has led advanced scouting efforts, been the Director of Player Development, and Director of the Innovation Department embedded within Research Development for the Chicago Cubs. Bobby runs the business side of the Union Baseball and oversees the development process, making sure it meets the same standards that professional baseball teams use.
Matt McLoughlin
Head of Pitching Development
A former DI college pitcher and native San Diegan, Matt has been a fixture on the San Diego amateur baseball scene as pitching coach for the San Diego Show.
