London: Serena Williams confessed to almost being overcome by the pressure of partnering British sporting icon Andy Murray in the Wimbledon mixed doubles, but it all worked out in the end as they won their first round match on Saturday, beating Germany's Andreas Mies and Chile's Alexa Guarachi 6-4, 6-1.

Seven-time singles champion Serena had fulfilled Murray's search for a partner — World No. 1 Ashleigh Barty had been previously mooted.
