As a native of Englewood New Jersey, Carlos Mirabal excelled in sports. At Bergen Tech High School, Mirabal displayed his athletic versatility by playing baseball, basketball, and football. Shortly afterward, Mirabal caught the attention of the New York Yankees while playing for an amateur league in Puerto Rico. He was signed by the Yankees to play in Single A, but a devastating elbow injury hindered his MLB dreams. Nevertheless, injury was not to be the end of Mirabal's baseball career. In fact, the situation would put on display hidden parts of Mirabal's character. The love of the game lead Carlos to play a season of independent baseball so he could rehab his elbow.
Then he traveled to Taiwan, where he played three years. The next leg of his travels lead him to Japan where he played for the Nippon Ham-Fighters for six years. As a pitcher, Carlos maintained a heavy workload during his time overseas. In the MLB, most pitchers throw 80 to 120 pitches. Mirabal regularly threw 165 to 199 pitches. Carlos Mirabal has continued his long-term love for baseball by actively engaging in various parts of the game. He's served as a pitching coach for Rockland Boulders, designed a pitching dome (The Carlos Mirabal Professional Pitching Dome), and assists younger ball players with their careers. He is a co-founder of the Japan Retired Foreign Professional Association.
