It appeared his array of sparkling winners had been ended by Murray's determined rearguard, which saw the three-time Grand Slam victor twice stave off break points to take the second set in 48 minutes.
Andy Murray is set to play Spaniard Feliciano Lopez later this afternoon.

Murray served to stay in the match at 4-5, but, when he went way long with a smash to hand Thiem a match point, the 23-year-old closed out the contest.
Nadal and Thiem have met on three occasions previously, on clay each time, and the young Austrian can draw inspiration from his victory over the Spanish great in Buenos Aries previous year, despite having lost their last meeting in Monte Carlo.
The Spaniard - victor of nine French Open title and widely considered the best clay court exponent the game was seen - produced a shot that was half-volley, half- self defence and all kinds of confusing.
