"Basically it was her day today," Erakovic said. "I tried to do all the right things and I tried to attack and dominate but she just got a lot of balls back. It is a tough one to take but I did the best I could today and that's all you can ask for.
"What it came down to I needed a little more sting on my shots and I didn't have it today. I tried my best to serve big and hit big and I hit a lot of winners and a lot of unforced errors."
There may have been 50 places between them in the rankings but the dirt is Dominguez Lino's home. The Spaniard was content to rally from well behind the baseline and the waiting game paid dividends.
The decisive moment came at 5-5 in the second set with Erakovic serving at 15-15. She failed to put away a smash and hit the subsequent volley wide. Reflecting on another early loss at Roland Garros, Erakovic was philosophical.
"You can't be too disappointed. I am playing good tennis, I am healthy and at Roland Garros last year I was playing qualifiers. If I continue improving, there will be a lot more grinders I will get on top of."
The ITF require Olympic nominations by June 14, three days after the French Open. Erakovic will point out the Olympics are being played on grass at Wimbledon, her best surface, and that she has risen more than 300 places in the rankings in the past year.
"Of course I would like to go [to the Olympics]," she said. "Grass is a surface I play well on and I have done well on. There are a lot of players from different countries around my ranking who are going so I don't know what the big issue is."
Erakovic is still in the French Open and is seeded 16th for the doubles together with her Romanian partner Monica Niculescu. They play the French wildcard pairing of Severine Beltrame and Laura Thorpe in the first round.
