Jason Sinnarajah named Nationals president of business operations

The Washington Nationals today announced the hiring of Jason Sinnarajah as the Club’s President of Business Operations. Sinnarajah will oversee all business-related aspects of the franchise.

Sinnarajah’s appointment is an important milestone in building the next generation of the Nationals organization, aligning the Club’s business and baseball operations under a new generation of leadership. He joins a front office that recently welcomed Paul Toboni as President of Baseball Operations and Anirudh Kilambi as General Manager.

“Jason is a transformative leader with a proven track record of using data and innovation to enhance the fan experience and drive organizational excellence,” said Nationals Managing Principal Owner Mark D. Lerner. “By creating the President of Business Operations role, we are ensuring that our business strategy is as modern and forward-thinking as our baseball strategy. We believe Jason is the ideal person to lead the Nationals into a bright future.”

Sinnarajah comes to Washington from the Kansas City Royals, where he served as Senior Vice President and Chief Operating Officer. During his tenure in Kansas City, he led a revitalization of the stadium experience, including the implementation of cutting-edge fan entry technology and a reimagined concessions program.

“I am honored and excited to join the Washington Nationals at such a pivotal moment in the franchise’s history,” said Sinnarajah. “The organization has a clear vision for the future—one built on innovation, excellence and a deep commitment to the fans and the D.C. community that my family and I are excited to make our home. I look forward to working alongside Paul and this talented staff to build an organization that benefits our players and our fans, and which sets the standard for organizations within and beyond Major League Baseball.”

"We appreciate Jason's contributions with the Royals and helping make the organization better,” said Royals Chairman and CEO John Sherman. “This is an exciting opportunity for Jason, and we wish him and his family well with the Nationals.”

Prior to the Royals, Sinnarajah served as Senior Vice President of Business Administration for the Buffalo Bills (2020-23), where he played a key role in the development of the team’s new stadium project and led ticket sales and marketing. His career also includes tenures with the Cleveland Guardians and five years at Google, where he led global media and sports partnerships, and worked to scale Google’s business operations across the Asia-Pacific region.

A native of Toronto, Canada, Sinnarajah earned a Master’s of Business Administration from the University of Virginia’s Darden School of Business and a bachelor’s degree in finance and marketing from Boston College. He and his wife, Jessica, have two sons, Taylor (14) and Matthew (11).
