A legend watches on...

SET! - GAVRILOVA 6-0 3-6 SUAREZ NAVARRO. Polite applause ripples around the RLA. Not what they wanted to see, in truth. Suarez Navarro has found her form and is now dictating most of the rallies. Gavrilova saves one set point to make deuce but can't find the defence to halt her opponent's powerful probing down both flanks and eventually drops serve again when she can only fire long of the baseline under pressure. It's one-set all and Daria will need to find something in her notes she likes to read at the changeover to conjure up the tactics to turn this back in her favour in the decider.

Big mistake from the Spaniard but kudos to Gavrilova for never giving up.

Wonder if we'll see another amusing reaction from Federer as he watcher in the locker room? The Swiss Maestro was/wasn't amused when Sharapova let Lauren Davis back into her match the other night... he's already had a heavy delay due to Djokovic's epic with Simon.
