Angelique Kerber expects CiCi Bellis to enjoy "a great future" after ending the young American's run at the US Open on Friday.
Australian Open winner Kerber, seeded second at Flushing Meadows, defeated the 17-year-old 6-1 6-1 in the third round.
Bellis is yet to turn professional and must give up the prize money she earns at the final grand slam of the year to remain eligible for college tennis.
But big things are expected of the Californian, with Kerber the latest authority to offer the youngster a ringing endorsement.
"I think she had a great tournament," the German told a media conference.
"She's a great, young, really talented player. For sure she will have a great future. I mean, she's a great player. She's really young, so let's see how her future will be. But I'm really sure it will be a good one.
"I think she went out there and she tried to play her game. I mean, she tried to move good. She's not making too many mistakes. So this is a really great weapon from her. Let's see.
"I think she was a little bit nervous at the beginning of the match. I know the feeling, so I was trying to [use] my experience tonight for this match."
Up next for the world number two is a meeting with two-time Wimbledon champion Petra Kvitova.
"It will be a good match," Kerber said.
"We had great matches in the past. It will be a good challenge. I'm looking forward to it. I will try to go out and win the match of course. Try to enjoy the next match here in New York."
