Ernests Gulbis and Aļona Ostapenko (known internationally as Jelena) are both through to the third round of the men's and ladies' competitions after good victories July 5.
Gulbis beat Damir Džumur of Bosnia and Herzegovina in five sets, displaying all of his erratic brilliance along the way.
Gulbis said he was feeling in good form."I do not want to sound conceited, but I have the weapons to beat all the strongest adversaries. I just need to arrange my head and find my rhythm, and then there will be wins," Gulbis said.
Meanwhile 12th seed Ostapenko had far less trouble disposing of Kirsten Flipkens of the Netherlands in two sets in under an hour, losing just four games along the way. She will be back on court July 6, teaming up with Christina McHale of the United States in the ladies' doubles competition before facing Russian qualifier Vitalia Diatchenko in the singles.
Despite crashing out of the singles on Monday, Latvia's other top player, Anastasia Sevastova, will also be in ladies' doubles action July 6 paired with Mandy Minella of Luxembourg.
