Jamie Murray was forced to do press-ups as a punishment by his hardline partner Taylor Townsend after their mixed doubles win at Wimbledon.

Britain’s Murray and American Townsend needed two tie-breaks, the second a marathon ending 15-13, to beat Nicole Melichar-Martinez and Jan Zielinski.

Murray had earlier won in the men’s doubles with Australian partner Michael Venus in three sets against Alexander Erler and Lucas Miedler.

But that gruelling schedule did not stop Townsend from making the Scot do a forfeit alongside her for not serving well enough.

“It was punishment for me to keep bloody serving in the net,” said Murray.

“I was like blowing it all of the time. She was like, ‘oh my God, we should do some press-ups’.

“She did outlast me. I said to her ‘keep going, I don’t want to fail in front of all of these people’. I was happy to bow out after 10. I don’t like them.”

British pair Joe Salisbury and Heather Watson are also through to the third round after beating Nathaniel Lammons and Giuliana Olmos.

But Katie Boulter and her Australian boyfriend Alex De Minaur were sunk in three sets by Joran Vliegen and Xu Yifan.
