"I hope I can keep the same energy in the next round" - Andreescu after advancing in Rome

The first career meeting between two of the last three US Open winners ended abruptly with Bianca Andreescu advancing to Round 2 after Emma Raducanu retired with a low back injury.

At the 5-2 changeover, Raducanu left the court for a medical timeout, and she completed just four more games before shaking hands. After dropping serve for a third time to trail 6-2, 2-1, the Brit pulled the plug, and told reporters later that the issue is one she's been dealing with since her third-round exit from Madrid. The Canadian explained that it was one of her better ones lately:

"It's definitely up there. Also, my match with Danielle Collins in Madrid was very good. In my opinion, 'very good for me is defined by consistency, effort, execution ... I do wish her a speedy recovery and hope I can keep the same energy in the next rounds."

Andreescu moves through to a second-round meeting against Spanish lucky loser Nuria Parrizas Diaz, who advanced when her compatriot Sara Sorribes Tormo retired with a left upper back injury while leading 6-1, 4-3 in the match.
