Theo Fightmaster to Lead Burgeoning Pro League

SAN FRANCISCO — The Pacific Association of Professional Baseball Clubshas formally named Theo Fightmasterthe league’s next Commissioner. Fightmaster, who began his Pacific Association career as a front office executive with the San Rafael Pacifics in 2011, also served as the general manager of the Sonoma Stompers from 2014 through the 2017 season.

During Fightmaster’s tenure the Stompers were on the cutting edge and garnered national acclaim for the organization’s innovative strategies. After Sonoma’s 2014 inaugural season, the Stompers partnered with former Baseball Prospectus contributors and managing editors, Ben Lindbergh and Sam Miller, to bring analytics to the front office and to the field. The story of the 2015 season was chronicled in the New York Timesbest-selling book “The Only Rule Is It Has to Work.” 

Additionally, in an effort to create more opportunities for women in professional baseball, the Stompers recruited Kelsie Whitmoreand Stacy Piagno. The Stompers also signed the game’s first openly gay player, Sean Conroy, in 2015. The team went on to win the Pacific Association championship that season, and enjoyed a better-than .600 winning percentage in the four seasons under Fightmaster. 

“Theo Fightmaster is someone who realized years ago, that to make an impact in the sports world, he would need to think outside the box,” said Billy Bean, Vice President & Special Assistant to the Commissioner of Major League Baseball. “His ability to bring progressive minded people together that work as a team caught my attention a few years ago. In that time, his name, while being one of the best in pro sports, has started to become synonymous with innovation. I can’t wait to see what he does next.” 

“The Pacific Association means a great deal to me, as do the people in it.” Fightmaster said. “We’ve put literal blood, sweat and tears into this league, and I hope to help usher in a period of continued growth and stability.

“This league has done so many incredible things in such a short period of time; from experimenting with robotic umpires, to five-man infields and giving opportunities to gifted players regardless of gender or sexual orientation. This league has launched a number of very promising baseball careers — on the field and in the front office — and I’m eager to see what’s next.” 

“The Clippers are looking forward to the 2019 season with Theo at the helm of the Pacific Association of Professional Baseball Clubs,” said Clippers owner, Paulette Carpoff. “We’re excited to have someone with his enthusiasm, as well as his innovative approach to the game. I’m confident that Theo is going to be a great asset to the league as we continue to grow.”

A lifelong Sonoma County resident, Fightmaster is a graduate of the Arizona State University, where he earned a Bachelor of Science degree studying at the Walter Cronkite School of Journalism and Mass Communications. In 2017 he was recognized by the North Bay Business Journal as one of the regions top 40 executives under forty. 


Founded in 2013 by four North American Baseball League teams, the Pacific Association now consists of six professional clubs; the Sonoma StompersSan Rafael PacificsPittsburg DiamondsVallejo AdmiralsNapa Silveradosand the Martinez Clippers. San Rafael has been crowned league champion three times. Both the Silverados and Clippers joined the fold in 2018 as the only independent league on the West Coast grew from four to six clubs. 

The league plays approximately an 80-game schedule between the end of May and early Sept. More than 100 players have been promoted from the ranks to higher professional leagues, and nearly a dozen have been signed by Major League Baseball organizations. 


Founded in 2018, the Martinez Clippers compete in the Pacific Association of Professional Baseball Clubs. The team is named for New York Yankee Joe DiMaggio, who was nicknamed "The Yankee Clipper" and was born in Martinez. Please follow us on the social media sites below.
