 Jose Acosta – Muckdogs 18U Red Fall/Winter Team Assistant Coach
Jose grew up in Carson City, Nevada, where his love for baseball began at Carson High School. From 1991–1994, Jose played baseball under Coach Ron McNutt, developing the competitive foundation and appreciation for the game that would continue to shape his life.
After high school, Jose pursued wrestling at Sierra College. Wrestling became an important part of his personal development, teaching him the value of discipline, resilience, accountability, and hard work. Those lessons would later prove invaluable both in his engineering career and in his approach to baseball and coaching. Wrestling taught Jose that success is earned through preparation, perseverance, and the willingness to continue working when things become difficult.
Jose continued his education at Western Nevada Community College, the University of Nevada, and ultimately Arizona State University, earning multiple engineering degrees. His academic and professional journey reinforced many of the same principles he learned through athletics: attention to detail, problem-solving, persistence, preparation, and the ability to overcome challenges.
Those experiences ultimately led Jose to pursue one of his long-time dreams, creating opportunities for young athletes to compete and believe in themselves regardless of where they come from. He founded the Diablos Baseball Club and Synergy Baseball in Dayton, Nevada, with the vision of showing young players that their hometown or the size of their community should never determine the level at which they aspire to compete.
Jose also helped Dayton High School as an assistant coach. While coaching was rewarding, he eventually stepped away for a few years because he wanted the opportunity to watch and support his own children as they competed and developed as athletes.
Now, Jose is ready to return to coaching and mentoring. His goal is not simply to teach the fundamentals of baseball, but to help young athletes develop the mindset required to succeed both on and off the field. Drawing from his experiences in baseball, wrestling, engineering, and raising a family, Jose believes that talent can open a door, but hard work, discipline, perseverance, and a willingness to compete are what ultimately allow an athlete to walk through it.
Through his continued involvement in youth baseball, Jose hopes to give athletes from Dayton and surrounding communities the confidence to dream bigger, work harder, and believe they can compete at the highest levels—no matter how small the town they call home.
In the fall of 2026, Jose took over as the Muckdogs 18U Red Fall/Winter Team Assistant Coach. He specializes in working with catchers and hitters.
