Britain, Kazakhstan and Croatia each advanced to the quarterfinals of the Davis Cup Finals by winning their groups on Sunday.
Britain beat the Czech Republic 2-1 to win Group C in Innsbruck, Austria, setting up a quarterfinal against either Serbia and top-ranked Novak Djokovic or a Germany team missing No. 3 Alexander Zverev.
Kazakhstan shut out 2019 runner-up Canada 3-0 to win Group B in Madrid, setting up a quarterfinal against a group runner-up.
Croatia beat Hungary 2-1 to win Group D and set up a quarterfinal against host Italy in Turin.
Each matchup on indoor hard courts is a best-of-three series featuring two singles and one doubles match. The six group winners plus the two second-place teams with the best records based on sets and games will advance to the quarterfinals.
The semifinals and final will be played in Madrid.
Later, the United States was playing Colombia, defending champion Spain was facing Russia and Germany was playing Austria.
BRITAIN 2, CZECH REPUBLIC 1
Joe Salisbury and Neal Skupski beat Jiri Vesely and Tomas Machac 6-4, 6-2 in the decisive doubles match to give Britain the 2-1 win.
After the 143rd-ranked Machac had upset No. 25 Dan Evans 6-2, 7-5 in the opening singles match, No. 12 Cameron Norrie defeated Jiri Lehecka 6-1, 2-6, 6-1 to even the series.
“Today was tough. You look at the rankings and a lot of people would think it’s going to be straightforward but it’s never like that,” Britain captain Leon Smith said. “The Czech team played really well today, they are a very good young team. Machac looked like he had suddenly turned into a top-20 player overnight.”
Still regaining in form after a series of physical issues, Andy Murray opted not to play for Britain.
Britain won the group, France finished second and the Czech Republic was third.
