Blake played some confident tennis as Murray struggled badly with his serve at the end of the first set and into the second.
Murray's frustration was evident as he committed a host of unforced errors allowing Blake complete an easy win.
After losing the first set, Murray needed to make a good start to the second set but he was quickly 2-0 down before an inspired cross-court pass helped him make it 2-1.
But again the serve let Murray down as Blake broke once more to restore the two-game advantage.
Murray made it 3-2 with a topspin lob but yet again Blake responded by breaking.
The final three games went with serve, and Blake took the first of three match points on serve to book a third-round meeting with Croatia's Mario Ancic.
