As the world No.126, while yet to emulate the same level of achievements in singles as doubles this year, he was assured of the flow-on effects.
“More than just winning those matches it gives me a lot of confidence towards singles, just in my game in general,” he said. “A winning feeling is always good and during those low moments in singles, getting a few wins in doubles is always really helpful.”
Kubler set for RG debut
Australian Jason Kubler will also make his Roland-Garros main draw debut after a 7-5, 6-2 victory over Borges’ compatriot, Pedro Sousa.
The world No.161 had contested qualifying in Paris three times before and required five match points to finally handle the weight of the moment and pass the final hurdle.

“It feels unreal. This was the last Slam where I hadn't played a main draw,” Kubler said. “With the match, right at the end was a bit nerve-wracking. I was definitely a bit tight.
“I think it's just something that's going to help my confidence that even when I'm feeling like that I can still get through. Yeah, I’m really happy with the last three matches.”
The 29-year-old saved a match point to deny Moldovan Radu Albot in the previous round in a three-hour and 14-minute tussle.
