Great Britain have crashed out of the ATP Cup despite ending their campaign with victory over the USA.
With the tie level at 1-1 after the singles matches, Dan Evans and Jamie Murray did what they had to do in defeating Taylor Fritz and John Isner 6-7, 7-5, 10-8.
That was enough to give them a chance of qualification from Group C, although they were reliant upon Germany beating Canada in the other match.
But wins for Denis Shapovalov over Jan-Lennard Struff (7-6 (5) 4-6 6-3) and then Felix Auger-Aliassime against Alexander Zverev (6-4 4-6 6-3) saw the Canadians advance instead to a last-four meeting with defending champions Russia.
Britain, who had beaten Germany 2-1 and then lost 2-0 to Canada earlier in the group, headed into their doubles showdown with the US after Evans beat Isner 6-4 7-6 (3) and Cameron Norrie was then defeated 7-6 (4) 3-6 6-1 by Fritz.
Evans and Murray had already won one deciding match against Germany and produced another impressive display.
Evans told the ATP's website: "Jamie talked me through the whole match. I don't call anything, he calls everything, I just go with it.
"It makes my job a lot easier when I have him everywhere, so I just run around basically and hopefully he mops it up."
Murray added: "We were just hustling. We just kept saying, 'Just try to get the ball back in play, start the point', and tried to use our skills after that.
"We played an amazing point to break back at 4-2, got a bit of momentum and played a great tie-break, which is ultimately what it comes down to so many times."
