Filip Krajinovic was involved in a heated debate with umpire Greg Allensworth after a controversial decision during a match against Adrian Mannarino at the Geneva Open.
During one of the rallies in the second set, where Mannarino was serving whilst 5-1 up, Krajinovic hit a wide shot that appeared to land near the line. Mannarino and the line judge proceeded to call the ball in and the players were about to get set for the next point.
However, Allensworth then came down from his umpire's chair to inspect the clay surface where the ball landed, overturned the decision, and awarded the point to Mannarino. In response, Krajinovic confronted Allensworth, to which the umpire asked whether the Serbian player was conceding the point.
"I'm not conceding the point. If it's out it's out, I don't care."
Instead of letting the decision go and moving on with the game, Krajinovic continued to argue his point and further questioned Allensworth about his methods of officiating.
"Doesn't matter, he's winning anyway. Doesn't matter about this match. Then you ask him, what he thinks. If he's decided if it's good or it's not. It's good. Why ask him? You asked him if he says it's in,"
Despite the short delay due to the incident, Mannarino eventually served out the match and won two of the resulting three points to advance to the second round of the Geneva Open.
