A good week for the Murray family at the US Open is turning into a brilliant one after Jamie battled to a final.
The elder Murray brother will now play in the mixed doubles final on Thursday in New York, after winning his semi with playing partner Liezel Huber.
They beat American pair Jill Craybas and Eric Butorac - who Jamie used to play doubles with too - 6-3 6-4.
Jamie is now one match away from a second Grand Slam title, after winning the Wimbledon mixed doubles in 2007.
Big brother Andy is back in action later on Wednesday when he takes on Argentine player Juan Martin del Potro, who has won his last 23 matches in a row.
And it could be a bit of a battle, as the two players had a big row in the middle of a match earlier this year.
