Nick Kyrgios was again involved in on-court controversy during his match against Andrey Kuznetsov at the Miami Open.
Kyrgios was trailing 3-0 when a ball girl threw him a ball to serve, which he promptly hit into the crowd, an action which earned the player a warning from the umpire.
That led to a heated exchange between the world No 26 and the match official, although it did not distract Kyrgios as he went on to beat Kuznetsov in straight sets.
"Anyone else, like Rafa [Nadal] did that, you would keep it cool," Kyrgios said.
"This game is biased as anything. You all know it as well. What else has it got to hide? It's ruined. Absolutely ruined."
The outburst comes just three weeks after Kyrgios was docked a point by an umpire and threatened to leave a match at Indian Wells.
