dialled in

The new line-up was announced on the Radio 1 Breakfast Show with Greg James when the couple dialled in to the station.

The world number 81 started superbly but had to withstand a Medvedev fightback, with the Russian frequently switching from irate to dialled in as he forced a fifth set.

"I wasn't really 100% dialled in on what I should be saying. Little slip of the tongue."

Although Muchova upped her level, Pegula was dialled in, rarely missing from the baseline, and she claimed a crucial early break before advancing as her opponent speared a shot long.

There was the occasional gesture towards his support box - who responded by telling him to keep his head up and stay positive - but on the whole, Djokovic was as dialled in as he has been all year.
