Cape Town - South African tennis star Raven Klaasen and his New Zealand doubles partner Michael Venus made a winning start at the ATP Finals in London on Sunday.
The fifth-seeded pairing beat fourth seeds Rajeev Ram (America) and Joe Salisbury (Great Britain) 6-3, 6-4 in 64 minutes, saving all four break points they faced.
It was Klaasen and Venus' second straight appearance at year-end finals and they improved to a 33-17 win-loss record in 2019.
The SA-Kiwi duo won ATP titles in Halle and Washington DC and also made the semi-finals at Wimbledon.
"We'll take that every day of the week," Klaasen told the ATP Tour's official website. "To be the first match of the Finals is a bit nerve-racking and to get off to a good start certainly puts our minds at ease for the rest of the tournament."
