Couple of passing shots from both players and they're locked in a good rally. There's a forehand lob from Zverev that goes past Federer, but the Swiss is in no mood to let breaks march up on him. He breaks back.
Mischa Zverev holds his first service game in the second. He'll want to redeem himself now and this is a good time to do it. Federer rushes the net and Zverev can't respond fast enough. He sends it wildly into the air - but manages a service hold.
