Some frustration creeping in for Shelton, who gets into an argument with the umpire over a serving clock issue.
“This is that debate about when the serve clock should be switched off by the chair umpire, when the serving motion begins,” Brenton Speed said on Nine.
“This is when Shelton looked up at the chair umpire on that point saying ‘hang on a minute, the serve clock’s run out here, that’s a time violation’.
“Some players manipulate it and maybe Shelton thinks Sonego’s walking a fine line.
Casey Dellacqua sides with the American star after the discussion.
“I’m with Shelton in terms of the chair umpire really making sure …you really have to have started your motion,” she said.
-“I think Tom Sweeney just needs to be on that, because once you set a precedent early on in a match, then everyone knows the rules.
“They know that you need to really have started your motion.”
