Daria Gavrilova's coach Craig Tyzzer was alerted by his daughter to the fact his handwritten coaching notes had been broadcast to an audience of millions during Gavrilova's three-set Australian Open loss on Sunday night. "Not a massive issue", insists Tyzzer, who would nevertheless have preferred his private correspondence to remain that way.
"I don't know what the rule is with regard to it, but I'll just ask the question," said the experienced Victorian coach, who will travel with Gavrilova this season. "There's nothing in there that I feel embarrassed about or that 'Dash' and I would be worried about, but it's just stuff that we use to prepare for matches, and for her to play with, that we'd probably like to keep between ourselves." 
While the coaching tips, which were written underneath some typed messages on a single page, were as benign as "you can and will outwork her", and "this is exactly where you should be", viewers condemned broadcaster Channel Seven on social media as Gavrilova spiralled to an emotional three-set loss to 10th seed Carla Suarez Navarro.
Cameras zoomed in on the notes in Gavrilova's bag - twice - after she had consulted them at one-set-all, as commentators discussed the content. What also should be noted is that Tennis Australia is now the host broadcaster of its home grand slam, and provides most of the vision for Seven and other tournament rights holders. On this occasion, there is believed to have been a combination of cameras from various sources on Rod Laver Arena.
"I'm not all over any privacy issues, but I think it's pretty disappointing by the broadcaster if they're showing stuff between the coaches and players that is private," said Tyzzer, adding that Gavrilova's co-coach Nicole Pratt had started the notes system for the soon-to-be world No. 32. "We obviously don't want that stuff out there; it's between us and Dasha, so the fact it's found its way on TV and into the newspapers, that's pretty disappointing in a lot of respects.
"If Dasha is in the public domain out there on court and whatever she does is able to be shown, then obviously that's all OK, and it's not a massive issue for me. But it's just stuff between us and we want to keep that in-house among our team, so the general public or other coaches or other people don't know what we're working on." "
The WTA allows coaches to come onto the court at changes of ends during tour events, but the practice is not permitted at grand slams. "Often it helps her just look at it and refocus on what she's trying to do and give her just a clearer perspective of how the match should go, or how she needs to go about playing tactically in the match," Tyzzer said.
"I haven't spoken to Dasha about it. If that's public domain and they're able to broadcast it, then I'll just talk to Dasha about keeping it a bit more secure, keeping those things a little bit closer to her so they can't be seen."
