Daniil Medvedev is thriving on the pressure of being the man to beat after dispatching Andy Murray in straight sets at the Miami Open on Saturday to edge closer to regaining his world number one ranking.

The Russian top seed served superbly against the Murray, 34, a three-time Grand Slam champion, to ease to a 6-4, 6-2 triumph at the Hard Rock Stadium and will face Spain’s Pedro Martinez next.
