Andy Murray was a home winner again as he began his campaign at the Barclays ATP World Tour Finals with a 3-6 6-3 6-4 victory over Tomas Berdych at London's O2 Arena.
It was Murray's first match on home soil since becoming a grand slam champion at the US Open in September and he was back in London three months after his golden Olympic moment at Wimbledon.
"It was a good atmosphere," said the third seed. "It's important in the last week of the year when everyone's a little bit tired to have that atmosphere and big crowd to give you that extra little push that you need to play good tennis. So it was good to be back playing in the UK."
Next up for Murray will be the most-anticipated clash of the group stages when he takes on new world number one Novak Djokovic, who survived a close first set against Jo-Wilfried Tsonga before pulling away to win 7-6 (7/4) 6-3.
