American tennis is finally on the rise after hitting a hard decline for the past 20 years. 

The last time an American man won a Grand Slam was in 2003 when Andy Roddick won the U.S. Open. On the women’s side, we’ve been spoiled with Serena and Venus Williams winning a combined 30 majors, but besides the two legends, only two other Americans won Grand Slams in the past 20 years (Sloane Stephens, 2017 U.S. Open, and Sofia Kenin, 2020 Australian Open).

Let’s face it – having Roger Federer, Rafael Nadal and Novak Djokovic at the top of the sport for years has made it difficult for other men to break through. But with the three greats nearing the end of their careers and dealing with injuries, some doors may open for the Americans. 

NBC spoke with American tennis legend Tracy Austin, who is feeling good about the direction American tennis is headed.

She said when Federer, Nadal and Djokovic competed in all the same tournaments, “there were so few players that got to win majors because those guys pretty much hoarded all the Grand Slams.”

“I'm feeling good about the men's tennis, better than I've felt in years because I think there are a number of names that I can say might be able to win a major in the future,” she added.

Austin, a former world No. 1, was the youngest tennis player to be inducted into the International Tennis Hall of Fame and remains the youngest U.S. Open women’s singles champion, winning the major at age 16.

While the women’s competition has seen a variety of winners, the majority of those are ranked within the top 10.

“With tennis being so much more international and still just the top 100 really involved in the conversation of majors and the top 10, most likely going to win majors, it's just spread out more and it's tougher for the Americans to get in that conversation,” Austin said. 

The good news is that there are currently seven American men in the ATP top 50 and eight American women in the WTA top 50, with a handful making it deep into Grand Slam draws. 

With the French Open, Wimbledon and U.S. Open right around the corner, let’s take a look at the top American players in American tennis:
