Australian sixth seed Alex de Minaur was involved in the protests at last month’s French Open but decided he did not want to take part at Wimbledon.
“I think the sense that we had at Roland Garros was everyone was on board, even though we didn’t, as a collective, achieve the numbers that we were looking for,” he said.
“I thought that Wimbledon made a big step in the right direction, and something that should be noted. So this is for me to acknowledge their big step.”
Germany’s Alexander Zverev, who claimed his first major win in Paris earlier this month, also decided to step back.
“I still want to be part of the players’ movement, but also I realised the media can’t really do anything about it, or can’t really change it,” said Zverev, who represented the players in talks with the Grand Slams at Wimbledon last year.
“It’s not good to take it [out] on someone that doesn’t have the power of control, so I’m doing half an hour [of media]. But I still hope for some change in tennis, for sure.”
This year’s Wimbledon singles champions will each take home £3.6m, up from £3m last year, while first-round losers will earn £80,000.
