Andy Murray said on Tuesday that his long return from injury has taught him to try not to get too stressed by the demands and pressures of top-level tennis. However, he did admit that his latest comeback might not last. "I'm always sort of telling myself - and maybe it's not the best mindset - but each match could be my last one, you know, that I play now," he said. "I want to make the most of every match that I play and each tournament that I get the chance to compete in." Murray made a winning return to action with victory over Benoit Paire at the cinch Championships in London. A much tougher opponent awaits in round two - Italian top seed Matteo Berrettini, the world number nine.
