“Solid win today. Very happy with our start so far,” Peers tweeted after completing victory in a brisk 64 minutes.

Peers and Kontinen won 83 per cent of their first serve points, almost the same percentage on their second, and saved all three break points they faced.

The duo have won 11 of their past 13 matches and will look to extend their winning record in London when they face Mahut and Herbert in their final round-robin match on Friday.
