Ball made his debut for Wales against Ireland as a second-half replacement and went on the start against France when Jones pulled out of the game with a foot infection.
And after watching Ball closely, Jones insists he sees no reason why the youngster can't add significantly to his three caps over the coming years after being thrown in at the deep end.
"Both opportunities he's had, he's held his own," said Jones. "Sometimes it's better when you come in late because you have less time to think about things and just get on with it.
"But the two showings he's had I think he's held his own very well and he's got a definite future in the red jersey.
"With the likes of Jake coming in and a few of the other young boys putting their hands up, there's definitely positives on the horizon."
