World number one Andy Murray beat Malek Jaziri in the round of 32 in straight sets at the Dubai Championships, in what was his first match in five weeks since his surprise Australian Open exit. The Scot also revealed that he had been diagnosed with shingles since his last-16 defeat to Mischa Zverev, so this 6-4 6-1 return to winning ways was even more impressive. The 29-year-old will now play Spain’s Guillermo Garcia-Lopez on Wednesday, though with Swiss pair Roger Federer and Stan Wawrinka still in the draw, claiming his first Dubai title will be far from straightforward.
