Emma Raducanu romped to a straight-sets victory over Olga Danilovic to book her spot in the last 32 of the Cincinnati Open.
The British number one marked her first match since Rafael Nadal’s former coach Francis Roig joined her team with a confident 6-3 6-2 victory.

After four breaks of serve between the pair in the opening six games, Raducanu came from 30-0 down to grab another for 5-3 in the first set.
