Shanghai: World number five Daniil Medvedev booked his place in the last 16 of the Shanghai Masters Sunday, overcoming tenacious Italian Matteo Arnaldi 5-7, 6-4, 6-4.

Medvedev broke early in the first set but 36th-ranked Arnaldi kept his cool to break back in the sixth game on an unforced error from the Russian.

Arnaldi broke again in the 12th game after Medvedev hit long.

The Russian's mood darkened under pressure from Arnaldi in the second set and he was slapped with two code violations and a point penalty after arguing with the umpire.

The 28-year-old former world number one recovered to take the match to a deciding set and came through after 2hr 44min.
