British number one Andy Murray staged a remarkable recovery to beat Russia's Mikhail Youzhny and reach the final of the St Petersburg Open.
Murray fought back from a precarious position against Youzhny
The 20-year-old Murray won 6-2 5-7 7-6 to book a fourth final spot of the year, against Fernando Verdasco.
Murray was 5-2 down in the decider but steeled himself to win the next three games, saving a match point on his own serve in the process.
The last two games went with serve before Murray won the tie-break 7-1.
"Of course, the match point was the key moment," Murray said.
"I thought I'd lost... When I won that key (point), he got nervous and made quite a lot of mistakes.
I hurried up, wanted to close it quickly... That does not work with Andy
"The game at 5-3 when I broke his serve was very important too.
"I hadn't broken him since early in the match but then I hit some good returns, he made a couple of mistakes and the match started to become even again."
Youzhny, who reached 30-0 when serving at 5-3 in the final set, said: "Two good serves and the match could have been in my hands.
"But I hurried up, wanted to close it quickly. That does not work with Andy. A double fault and then I twice hit the net - and the game slipped away."
Fortune had been on Youzhny's side in the second set, when he broke Murray's serve for the first time with the help of a controversial decision.
On set point, Youzhny's shot was clearly out but was ruled in.
Murray was outraged by the decision but could do little to change the outcome as he had already used both his Hawk-Eye challenges in that set.
Verdasco, the left-handed Spaniard who Murray beat in the Australian Open at the start of the year, was a 6-2 6-3 winner over Croatia's Marin Cilic.
Murray, ranked 16, is 14 places above Verdasco and a win over the Spaniard on Sunday would keep him on course for one of the remaining places in the season-ending Masters Cup.
Next week's Masters Series tournament in Paris is the last chance to earn qualifying points.
Murray won his second career title in San Jose in February and was runner-up at Doha and Metz.
