The Canadian Open has approached the latter stages, with the quarterfinals set to get underway in Toronto.

Following a walkover in his match with Francisco Cerundolo, top seed Alexander Zverev advanced to the last eight, where he’ll face defending champion Alexei Popyrin.

Second seed Taylor Fritz will play Andrey Rublev, while Ben Shelton will meet Alex de Minaur in a top-ten showdown.

Making up the fourth quarterfinal is a clash between Alex Michelsen and Karen Khachanov, who will go toe-to-toe for the second time this year.

With a strong American presence in the second week of the tournament, something has happened on the ATP Tour which hasn’t occurred for over two decades.

After compatriots Fritz, Shelton and Michelsen advanced, there will now be three US players appearing in the quarterfinals of a Masters 1000 event for the first time since 2004.

The last time was at Indian Wells 21 years ago, where Andre Agassi, Andy Roddick, and James Blake all booked their place in the last eight.

None of Agassi, Roddick, or Blake went on to make the final, however, which ultimately featured Roger Federer and Tim Henman.

The success of American men’s tennis currently on the ATP Tour

Currently, 13 Americans are ranked within the world’s top 100, with seven of them taking up spots in the top 50.

Michelsen, Sebastian Korda, and Brandon Nakashima make up ATP numbers 34, 33, and 32, respectively.

Ahead of them are former Grand Slam semifinalists Frances Tiafoe and Tommy Paul, who have both cracked the top ten before.

Flying the flag near the very top of the rankings are world number seven Shelton and number four Fritz.
