After a marathon rally on match point, a desperate Erne sends the ball flying back to the opposite sideline. The referee calls it out. One team is absolutely certain the miracle save landed in, while the other is convinced it sailed long.
Moments like that have long been part of pro pickleball, and they rarely end with everyone satisfied. For 2026, Major League Pickleball brought OWL into its challenge system so these kinds of moments can be settled in real time and with confidence.
Here's how it works during a match, and what MLP's season showed about bringing live measurement to a sport growing this fast.
Quick answer
Major League Pickleball uses OWL for live line calls inside its in-match challenge system. OWL measures where the ball landed relative to the line and gives that evidence to the referee, who makes the call. OWL never overrules an official. The same measurement powers an on-air 3D replay of where the ball landed, so fans can see why a close call went the way it did while the match is still going.
Why Did Pro Pickleball Need Help With Line Calls?
Close line calls had become one of the most argued-over parts of the pro game. Players have traditionally made many of their own line calls, with referees and challenges there to settle disagreements. As prize money, rankings, and broadcast audiences grew, a single close call started to carry a lot more weight.
Line calls were a visible issue at the top of the sport heading into 2026. Every disputed one also played out on broadcast, where viewers could rewatch a ball the players only saw once, at full speed.
MLP wanted objective evidence in those moments, from a system that could keep up with a full league season.
What Did MLP and OWL Announce?
In December 2025, MLP announced it would join OWL's Trailblazer Program and use OWL for line calling and its in-match challenge system during the 2026 season, working alongside the league's existing match referees. The league said the technology would debut at the Carvana PPA Tour event in Zion, Utah, in March 2026.
MLP Commissioner Samin Odhwani described the partnership as a way to "enhance the reliability of our challenge system and the overall production quality of the on-court product."
How Does OWL Support Line Calls?
OWL measures where the ball landed relative to the line. In pickleball, that's the whole question: in or out.
It runs on the same kind of broadcast cameras MLP already works with. The league set up additional cameras for OWL, but it didn't have to buy specialty hardware its crew had never used. Those cameras feed OWL directly. OWL isn't working from the broadcast that goes out to viewers.
This is OWL Officiate. It gives officials officiating-grade measurement on an objective question, and every measurement comes with the frames behind it, so the evidence can be checked. For the idea underneath it, read Live Video Intelligence, Explained.
Who Makes the Call?
The referee makes the final call. OWL settles the physical question of where the ball landed, and the official rules with that measurement in front of them. It's one input into a human decision, the same way a replay angle is. Because OWL shows the frames behind every measurement, anyone can see what the call was based on.

What Does It Mean for the Broadcast?
The same measurement that helps the referee can help the broadcast tell the story. A close call is one of the most emotional moments in a match, and it's usually when fans want an explanation most.
Once OWL has the in or out call, it generates a 3D rendering of where the ball landed. That rendering goes on air, so the players and the audience can see the challenge from every angle. The referee and the broadcast are working from the same measurement.
What Can Other Leagues Learn From MLP?
A few things from MLP's season carry over to any league looking at officiating technology.
Start with an objective question. Where did the ball land relative to the line? This is exactly the kind of moment an objective measurement can settle.
Build around the process you already have. MLP leans on OWL for objective measurements that augment the referees' decision-making process.
Keep the official in charge. Players, coaches, and fans should know who makes the call and what evidence it was based on.
New Jersey 5s won the 2026 MLP championship to close the season. For OWL, it was a season of live line-call officiating inside a professional league.
Frequently Asked Questions
Does Major League Pickleball Use Line-Calling Technology?
Yes. MLP uses OWL for live line calls inside its in-match challenge system, working alongside the league's existing match referees.
Does It Need Special Cameras?
No specialty hardware. OWL runs on the same kind of broadcast cameras MLP already works with. The league set up additional cameras that feed OWL directly, separate from the broadcast viewers see. See how Officiate works.
Who Makes the Call?
The referee. OWL measures where the ball landed, and the official makes the ruling. OWL never overrules an official.
What's the Accuracy Rate?
We don't publish one headline number, because accuracy means something different for a line call than a rotation count. We publish the evidence: every measurement comes with the frames behind it.
If OWL Gets a Read Wrong, Who's Responsible?
The official makes the call. That's the design, not a technicality. OWL is one input into a human decision, the same as a replay angle.
