Fleming partnered Jamie Murray at Wimbledon in 2006
Colin Fleming says he hopes his call-up to the Great Britain team to face Ukraine in the Davis Cup will help him boost his world ranking.
The Scot, currently ranked 585th in the world but 11th in Britain, was called into the squad as a back-up following fears over Andy Murray's fitness.
"My ranking just started at the end of the summer, so it's a little bit false in those regards," said Fleming.
"But I just need to go out and win matches and bring it up."
Fleming, 24, will join Murray and doubles specialist Ross Hutchins for the Davis Cup tie in Glasgow on 6-8 March, along with Josh Goodall and Chris Eaton.
It's great to be a part of it, even though I'm sitting in the wings, but if I get my opportunity to play then I'll be ready to go
Murray, who withdrew from the Dubai Championships with a virus, is doubtful after being told by Dubai medical staff to rest for seven to 10 days.
"I'm grateful to be involved in the squad, and if I can come in do a job in either the singles or the doubles, I'll be ready to go," said Fleming.
"It's great to be a part of it, even though I'm sitting in the wings, but if I get my opportunity to play then I'll be ready to go."
James Ward, Dan Evans and Alex Slabinsky were the other players involved in the selection play-offs.
Ward and Fleming are both being taken to Glasgow as back-up, in case Murray does not recover in time, although Fleming would be the more likely replacement because of his doubles ability.
Fleming added: "One of my strengths is my ability to play both singles and doubles. In a competition like the Davis Cup with a four-man team, it can be an advantage to have players like that.
"I had some good success towards the end of last year winning some tournaments in singles and doubles, so more of the same this year and my ranking should progress in the right direction."
