Sorana Cirstea, who beat Monica Puig in the first round in Miami, said that she is very happy to be back playing good tennis again.
The 26-year-old Cirstea reached the 2009 quarterfinals at Roland Garros and the 2013 final in Toronto, beating Caroline Wozniacki, Jelena Jankovic, Petra Kvitova and Li Na before losing to Serena Williams.
But the Romanian fell below the Top 200 in 2015, when her shoulder was in great pain.
