As more tournaments around the world opt for electronic line-calling systems instead of human line judges, seven-time Grand Slam champion Mats Wilander says tennis is losing its intrigue and personality and is in danger of becoming an esport.
The Australian Open replaced on-court officials with the electronic system at the year's first Grand Slam and U.S. Open organizers said they would use the technology on all courts during the year's final major.
"I like line umpires and I liked the challenge system where we had three challenges," Wilander told Reuters.
