After retiring from tennis, Baker moved into Corporate Finance for a bank,[3] whilst also being a part-time television pundit for Eurosport and the BBC.

Their mother Judy Murray counselled the Bakers that the best way to progress, would be for Jamie to leave home and move to the LTA Tennis Academy in Loughborough.

Baker made his debut for the Great Britain Davis Cup team in September 2006 in the crucial relegation play-off against Ukraine.

He disposed of 9th seed (Q) Yuri Shukin 6–2 6–0 and then battling past Alexander Peya 6–4 7–6 to reach the final round where he defeated Daniel Köllerer 6–4 6–4.

Argentina had won their last ten home encounters 5–0, so Baker prevented the 2006 finalists taking their 11th successive 5–0 victory.

[2] Baker contracted Idiopathic Thrombocytopenic Purpura (ITP) in April,[5] and had to spend three days in intensive care in Florida.

[8] Baker partnered fellow Briton Chris Eaton at the start of the year, the pair winning the Glasgow futures event.

[9] Rather than begin the year in Australia trying to qualify for the Australian Open, Baker chose to play in Futures events in the United Kingdom.

[12] The new Davis Cup Captain Leon Smith selected Baker to take part in Great Britain's vital Davis Cup tie vs Turkey, at Eastbourne, in July alongside James Ward, Ken Skupski, Colin Fleming and Alex Ward(non player).

[13] In March, Leon Smith announced his team for the Euro/Africa Zone Group II tie against Tunisia, but he sprang a surprise, omitting Alex Bogdanovic, having recalled the 26-year-old to the squad after a three-year absence.

Although Bogdanovic (No 374) had lost all six of his live Davis Cup rubbers, he had at least won a Futures tournament in the United States this year.

[14] Baker lost his opening singles match, but won his dead rubber, contributing to Great Britain's 4–1 victory.

In December, Baker spent nearly a month with his close friend Andy Murray at his luxurious winter training base in Miami,[2] along with James Ward, Ross Hutchins and Oliver Golding.

There was success in the preliminaries in Nottingham and at Queens, and then for his last match, defeat in the second round of Wimbledon qualifying, against Igor Kunitsyn, a Russian baseliner who had once been in the top 50.
