Kyrgios called for the trainer during the second game of the third set, at one point even asking a ball boy to stretch out his right arm.He needed a medical time-out at the ensuing changeover.
"I wasn't feeling it at all and then on one serve I lost power in my arm. Just on my serve," Kyrgios complained.
"One serve, then completely dead. It's so dead and numb. It's incredibly weak.
"It's just so annoying."
A finalist at the Cincinnati Masters the week before the Open, Kyrgios couldn't believe his luck at the timing of his latest injury.
He must have felt the world was against him when umpire Carlos Ramos issued a code violation against him after a linesman reported the 22-year-old swearing.
Strictly, he did but the penalty seemed farcically harsh, with Kyrgios merely remonstrating with himself in exasperation on his way to a changeover.
"I didn't swear. You can't give me a code. You don't even know what I said," Kyrgios said.
Ramos said he believed Kyrgios.
"But I need to believe him too," the umpire said. "I cannot repeat what he said you said."
"Man, this is ridiculous. What is this? This is a joke," Kyrgios added before going on to drop serve again to hand Millman a two-sets-to-one advantage.
With full power, Kyrgios promptly obliterated his racquet, drawing a second code violation and a mandatory point penalty to start the fourth set.
Living on the edge, Kyrgios saved a series of break points in his first service game of the set.
The writing was on the wall when Millman eventually rifled a backhand past his half-hearted countryman to forge ahead 2-0.
There was no way back as Kyrgios surrendered the match after two hours and 15 minutes.
"It's a victory, but a hollow victory," Millman said."I know in the back on my mind his shoulder deteriorated at the match went on."He's a teammate. I feel for him. I really do."
