Kyle Edmund and Dan Evans pushed their claims for a place in Great Britain's Davis Cup final team by both winning titles on the same day.
Captain Leon Smith will name his team on Tuesday for the clash with Belgium in Ghent, and the decision of who will fill the second singles spot behind Andy Murray has become a very tricky one.
James Ward appeared to be the favourite because of his record in the competition and having returned to form with a Challenger title in India recently.
But he has won only one match during a trip to South America with Smith, who watched as Edmund claimed his first Challenger crown on clay thanks to a hugely impressive 6-0 6-4 victory over experienced Argentinian Carlos Berlocq.
That must surely put 20-year-old Edmund in pole position to make his Davis Cup debut on the clay at the Flanders Expo.
Evans has done all that he can and is the man in possession having been preferred to Ward for the semi-final against Australia in September.
He won his first Challenger title in six and a half years on Sunday, defeating 17-year-old American Frances Tiafoe 5-7 6-1 6-3, and will climb back into the top 200 on Monday from a low of 763 only four and a half months ago.
What counts against Evans is his relative weakness on clay, with Sunday's title in Knoxville coming on a hard court.
The likelihood is at least two of the three will be named in the team on Tuesday, with Smith not required to finalise his four-man line-up until the draw a week on Thursday.
Another potential option is Aljaz Bedene, with Jamie Murray saying he would welcome the 26-year-old into the team for the final "with open arms".
Bedene will put his case to the International Tennis Federation board on Tuesday after a change in the rules last year made him ineligible to compete for his adopted country in Davis Cup.
He was in the process of applying for a British passport last September when the ITF announced players would no longer be able to compete for two different countries from January 2015.
Because he had previously played three dead rubbers for Slovenia, his hopes of representing Britain appeared to have been dashed.
Bedene received his British passport in March and has been fighting his corner ever since, with his first appeal rejected by the Davis Cup committee in May.
He has not allowed the disappointment to affect his tennis and has had the best season of his career, reaching number 46 in the rankings.
That makes him a very attractive option to support Andy Murray, particularly because clay is his favourite surface.
Andy has been broadly supportive of Bedene's cause and used him as his practice partner while he was training on clay at Queen's Club earlier this week.
Both Murray brothers are certainties for the team and, after winning his opening match at the ATP World Tour Finals in London, Jamie backed Bedene's claims.
The 29-year-old said: " I hope for his sake that he's eligible to play. He's obviously done the right process, cleared all the obstacles that needed to be cleared. Obviously they decided to change the rules a couple of months before he's able to participate in Davis Cup.
"If he gets the green light, for me, if he does get selected, I'll welcome him with open arms. He's British, he's done what he needs to do. I'm sure he'll be a valued member of the team."
Even if Bedene is not available to play in Ghent, he will know he has helped the team after proving the perfect practice partner for Andy.
The world number two said of his new compatriot: "He's really nice, very quiet, hard worker, gets on with it. He has a very good attitude and he's also a fantastic player.
"He's ranked in the 40s so it's great for me to be able to practise with him because for the last few years I haven't had someone of that level to practise with around here.
"He'll probably continue to improve as well. I don't think he's at his limit. Hopefully he can kick on next year."
