Milos Raonic takes on Gael Monfils in tonight's evening match with live commentary on 5 live sports extra.
Tomorrow, attention switches to the John McEnroe Group with Stan Wawrinka playing Kei Nishiori in the afternoon session and Andy Murray headlining with a clash with Marin Cilic in the evening.
Plenty to look forward to, but that is all from this page today.
Piers Newbery's report - fresh from the O2 - is live alive-oh on the BBC Sport website.
Bye for now.
