ATP Cup 2020: Friday Tennis Scores, Results and Final Schedule

Serbia saw off Canada in the 2020 ATP Cup quarter-finals on Friday to join Russia and Australia in the final four, while Rafael Nadal's Spain survived a scare against Belgium.

The Serbs enjoyed a clean sweep in their tie, kicked off by Dusan Lajovic's straight-sets victory over Felix Auger-Aliassime.

Novak Djokovic came from a set down to beat Denis Shapovalov to secure their passage, and Viktor Troicki and Nikola Cacic then eased past Peter Polansky and Adil Shamasdin in the doubles to round it out.

Spain got off to a promising start as Roberto Bautista Agut kicked things off with a win over Kimmer Coppejans in their first rubber against Belgium, but David Goffin levelled proceedings when he upset Nadal.

Nadal and Pablo Carreno Busta then had to come from a set down to beat Sander Gille and Joran Vliegen in the doubles.

Serbia will take on Russia in Saturday's first semi-final, before Australia face off against Spain.

In the first quarter-final Lajovic eased past Auger-Aliassime without too much difficulty, breaking the Canadian on three occasions, while his opponent failed to convert either of his two break-point opportunities.

As Record's Jose Morgado demonstrated, the Serbian capitalised on a sloppy performance from his opponent:

Canada's prospects improved when Shapovalov, who had only won one set in his four prior meetings with Djokovic, kicked off their match by taking the first set with a break in the penultimate game.

The world No. 2 then had to save three break points at 1-1 in the second, but he did so in style:

He eventually managed to hold as he rattled off five games in a row to force a decider.

Djokovic was serving for the match at 5-4, but he was broken after a pause in play—in which he gave water to a fan in the crowd who had fallen ill—as Canada turned things around:

The 32-year-old held on for a tiebreak, though, and after Shapovalov had saved four match points, Djokovic claimed his victory at the fifth attempt.

In the doubles, Cacic and Troicki needed just 58 minutes to secure their win over Polansky and Shamasdin.

Bautista Agut made light work of Coppejans in Spain's opening rubber against Belgium, breaking his opponent four times in a straight-sets win.

Nadal had the chance to book their spot in the final four in the second rubber, but the world No. 1 was not at his best and Goffin duly capitalised with some fine play of his own:

The 33-year-old had rallied from a break down to force a second-set tiebreaker, but Goffin's victory never looked in doubt.

There was nothing to separate the two doubles pairs in the first set of the decisive third rubber, in which there was not a single break point for either side.

The second set was similarly tight, until Spain made a late breakthrough with the help of a video review:

That set up a match tiebreak, which Spain won thanks to a double-fault from Vliegen.
