Stan Wawrinka took Switzerland to the Davis Cup Finals group stage on Saturday, winning a rollercoaster deciding clash against Germany, just weeks shy of his 38th birthday. 

Three-time Grand Slam title winner Wawrinka, who helped the Swiss to the Davis Cup title alongside Roger Federer in 2014, defeated Daniel Altmaier 6-3, 5-7, 6-4 as his country triumphed 3-2 in their qualifying tie.
