Rafael Nadal has marked his return to the ATP Tour with a straight-sets win over Pablo Cuevas at the Cincinnati Open.
The Spaniard reached the semi-finals of the Olympic Games but he had not played a match on the main tour since encountering wrist problems at Roland Garros.
However, he continued his recent form by sealing a 6-1 7-6 victory over world number 19 Cuevas who failed to break Nadal's serve throughout the 90-minute contest.
Nadal will face Borna Coric in the last 16 after the Croatian beat Nick Kyrgios.
