UTR Sports, Baseline Vision Partner to Expand Electronic Line Calling
March 25, 2026
Miami, Fla. (March 24, 2026) – UTR Sports, the global leader in racquet sports ratings and technology and operator of the UTR Pro Tennis Tour, has announced a partnership expansion with Baseline Vision to integrate real-time data streaming and electronic line calling (ELC) into the UTR Pro Tennis Tour (UTR PTT) worldwide.
The partnership builds on a successful 2025 pilot held at more than 80 UTR PTT events across the U.S. and Europe. The multi-year partnership marks a significant step toward making officiating more efficient and providing an upgraded experience for players and umpires globally.
Baseline Vision is a portable, AI-powered system that brings real-time line calling, performance stats, and video analysis to any court without the need for pre-existing infrastructure, such as external power or internet. It’s ideal for ease of setup and travel, and there is no requirement for additional devices to be in the hands of chair umpires.
ELC and real-time data for UTR PTT events will be expanding into the Asia-Pacific region and additional locations in the U.S. and Europe, including at more college venues than in 2025. Players and officials will receive instant, objective feedback on close calls, reducing disputes and improving the quality and flow of competition. UTR Sports will further integrate Baseline Vision’s player and ball-tracking data into its analytics offerings, unlocking new insights to positively impact player skill development and performance.
“The teamwork during the pilot phase and the progress Baseline has made over the past 12 months has made them a trusted partner,” said Mark Leschly, CEO and Chairman of UTR Sports. “This expansion and integration into our operations and technology is another example of UTR Sports providing the most relevant solutions to players and providers worldwide. By working with Baseline Vision, we’re able to scale professional-grade officiating across our global tournament ecosystem.”
“We are thrilled to extend our partnership with UTR Sports,” said Michael Chojnacki, Baseline Vision Co-Founder and CEO. “Their global reach and dedication to using technology to grow the sport align perfectly with our mission. Electronic line calling has traditionally been limited to the highest-level ATP and WTA tournaments due to affordability and complexity. Our system provides professional-level accuracy at a cost-effective price point.”
