The young American men are coming up fairly fast, but it is hard to know when the boys will win some major tournaments.

Players like Jared Donaldson, Frances Tiafoe, Ernesto Escobedo and Taylor Fritz show great promise but they have a ways to go before advancing from the top 90 to 130 range into the impact player group

Forget about the Grand Slams right now — it is very early. Nobody knows if they are good enough to beat spectacular players like Roger Federer, Rafael Nadal, Novak Djokovic, Andy Murray and Stan Wawrinka.  

Let’s look the veteran Americans, who are pretty good, but not good enough.

Way back when, the Americans dominated: Pete Sampras, Andre Agassi, Jim Courier and Michael Chang. After they all retired, Andy Roddick was darn good, too. But that was the last one. In 2003, Roddick won the US Open. Since then, no Americans won it again.

Now, it is 2017, almost 15 years gone dry.

Currently, the American guys – John Isner, Sam Querrey, Steve Johnson and Donald Young – have not reached the semifinals at the Grand Slam. Ever. Even though he’s only 24, Jack Sock may be the U.S. man at No. 17, but he has also not shown the promise of rising Alexander Zverev and Nick Kyrgios.

In fact, they haven’t won an ATP 1000.

Time to change?

On Sunday at Miami, the very young American Donaldson will face against the huge-hitter Canadian Milos Raonic. Sock, who reached the semis at Indian Wells. He is coming up, better and better, and will play Jiri Vesely

On Monday, John Isner will face the boy-wonder Zverev. Will the German show why he’s ranked the spots higher than the American?

Querrey has a legitimate shot against Roberto Bautista Abut.
The American vets do like Miami, so perhaps they can go very deep and possibly win it all?
Maybe, but they have to prove it.

NOTES
Bethanie Mattek-Sands is playing well again and she has a fine shot against Mirjana Lucic-Baroni, but given that Lucic-Baroni played incredibly well by stunning Aga Radwanska, it will be a very intense contest.

Also on Sunday, Venus Williams and the 19-year-old Taylor Townsend will play against different foes and may face off in the fourth round. Venus is the favorite in that potential clash.

Tough one for Shelby Rogers, who has to play against No. 1 Angie Kerber.
